Hi Authors,

In draft-sd-l2vpn-evpn-overlay-03 draft, i think on the= whole the process is clear, but how to construct EVPN BGP routes is not de= tail described.
In EVPN network, MPLS Label is carried in Ethernet Auto-Discovery (A-D) rou= te,MAC/IP advertisement route,ESI Label Extended Community. In NVO3 network= , it is based on native IP, so all this MPLS Label should be replaced with = IP address. All process relies on MPLS label in EVPN should be modified to adapt to NVO3 network, such as sp= lit horizon, unicast traffic forwarding,load balancing and aliasing,and etc= .

So i hope this draft had better provide more detail des= cription about EVPN routes format and corresponding procedures.

Thanks

The purpose of the review is to catch significant issues before the I-D advances to IETF last call and IESG evaluation. This document seems fine to me and I only have three nits. I will start the IETF last call and raise these nits as last call comments and you can address them with any other comments you receive. Thanks for the work, Adrian === Section 2.2 has An E-Tree service has one or more Root ACs and many Leaf ACs. I suggest that "many" is not a necessary part of the definition although it may be probable in deployments. For the definition I think you need: An E-Tree service has one or more Root ACs and at least one Leaf AC. --- Section 2.3.1 para 2 s/fame/frame/ --- Figure 1 shows two notations "E-Tree". The associated arrows do not make it clear what is the extent of the E-tree since the top one and the bottom one show different edge points. Can you tidy that up?

Hi Authors,

In draft-sd-l2vpn-evpn-overlay-03 draft, i think on the whole the= process is clear, but how to construct EVPN BGP routes is not detail descr= ibed.
In EVPN network, MPLS Label is carried in Ethernet Auto-Discovery (A-D) rou= te,MAC/IP advertisement route,ESI Label Extended Community. In NVO3 network= , it is based on native IP, so all this MPLS Label should be replaced with = IP address. All process relies on MPLS label in EVPN should be modified to adapt to NVO3 network, such as sp= lit horizon, unicast traffic forwarding,load balancing and aliasing,and etc= .

So i hope this draft had better provide more detail description a= bout EVPN routes format and corresponding procedures.

Thanks

Please send substantive comments to the ietf@ietf.org mailing lists by 2014-07-15. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This document describes an Ethernet-Tree (E-Tree) solution framework for supporting the Metro Ethernet Forum (MEF) E-Tree service over a Multiprotocol Label Switching (MPLS) network. The objective is to provide a simple and effective approach to emulate E-Tree services in addition to Ethernet LAN (E-LAN) services on an existing MPLS network.

I suggest that "many" is not a necessary part of the definition although it= may be probable in deployments. For the definition I think you need: An E-Tree service has one or more Root ACs and at least one Leaf AC. [Lucy] Since one key of E-tree service is prohibiting the communication bet= ween leaf ACs. Therefore, one leaf AC case does not make sense. How about: = An E-Tree service has one or more Root ACs and at least two Leaf ACs.=20 --- Section 2.3.1 para 2 s/fame/frame/ [Lucy] will change it. Thanks. --- Figure 1 shows two notations "E-Tree". The associated arrows do not make it= clear what is the extent of the E-tree since the top one and the bottom on= e show different edge points. Can you tidy that up? [Lucy] I'll fix it.

This draft is a work item of the Layer 2 Virtual Private Networks Working Group of the IETF. Title : MAC Address Withdrawal over Static Pseudowire Authors : Siva Sivabalan Sami Boutros Himanshu Shah Sam Aldrin Mannan Venkatesan Filename : draft-ietf-l2vpn-mpls-tp-mac-wd-00.txt Pages : 8 Date : 2014-07-01 Abstract: This document specifies a mechanism to signal MAC address withdrawal notification using PW Associated Channel (ACH). Such notification is useful when statically provisioned PWs are deployed in VPLS/H-VPLS environment. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-l2vpn-mpls-tp-mac-wd/ There's also a htmlized version available at: http://tools.ietf.org/html/draft-ietf-l2vpn-mpls-tp-mac-wd-00 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.

They did not warrant holding up IETF last call, but can be fixed along the way... Cheers, Adrian === Section 2.2 has An E-Tree service has one or more Root ACs and many Leaf ACs. I suggest that "many" is not a necessary part of the definition although it may be probable in deployments. For the definition I think you need: An E-Tree service has one or more Root ACs and at least one Leaf AC. --- Section 2.3.1 para 2 s/fame/frame/ --- Figure 1 shows two notations "E-Tree". The associated arrows do not make it clear what is the extent of the E-tree since the top one and the bottom one show different edge points. Can you tidy that up? > -----Original Message----- > From: L2vpn [mailto:l2vpn-bounces@ietf.org] On Behalf Of The IESG > Sent: 01 July 2014 15:09 > To: IETF-Announce > Cc: l2vpn@ietf.org > Subject: Last Call: (A Framework for > Ethernet Tree (E-Tree) Service over a Multiprotocol Label Switching (MPLS) > Network) to Informational RFC > > > The IESG has received a request from the Layer 2 Virtual Private Networks > WG (l2vpn) to consider the following document: > - 'A Framework for Ethernet Tree (E-Tree) Service over a Multiprotocol > Label Switching (MPLS) Network' > as Informational RFC > > The IESG plans to make a decision in the next few weeks, and solicits > final comments on this action.

Therefore, one leaf AC case does not make sense. How about: An E- > Tree service has one or more Root ACs and at least two Leaf ACs.

Hi John,

Thanks for your quick answer.

 

OK, section 5.1.3 describes how to con= struct  EVPN BGP Routes, the MPLS Label field in the MAC Advertisement= , Ethernet AD per EVI, and
Inclusive Multicast Ethernet Tag routes is used to carry the VNI or VSID.

 

As for section 8.3.1, split-horizon me= chanism relies on tracking other NVEs ip address, each ingress NVE only use= s a single IP address for split-horizon, as opposed to requiring an IP addr= ess per Ethernet
Segment per NVE.  I think a single IP address can't s= atisfy the requirements in the following scenario.
            &nb= sp;            =        +-----------+
            &nb= sp;            =        |   Router  |
            &nb= sp;            =        +-----------+

      &n= bsp;            = ;            &n= bsp; |     |    |
            &nb= sp;            -----= ---      |     --------
            &nb= sp;           | &nbs= p;            | = ;            |
            &nb= sp;         +------+ &= nbsp;    +-------+      = 3;------+
            &nb= sp;         |(NVE1) |  &n= bsp;  |(NVE2) |      | NVE3 |
            &nb= sp;         +------+ &= nbsp;    +-------+      = 3;------+
            &nb= sp;           * &nbs= p; |         *  |  ^ = ;       * |  ^
            &nb= sp;           * &nbs= p; |         *  |  ^^^^^^= ^^^^^^^^^^
            &nb= sp;           * &nbs= p; ----------*--------------*-|     ^
            &nb= sp;           ***********= ******************* |        ^
            &nb= sp;   MC-LAG1 *        &n= bsp;            = ; MC-LAG2 | MC-LAG3   ^
            &nb= sp;       +------+   &= nbsp;           &nbs= p;       +------+    &= #43;------+
            &nb= sp;       |  CE1 |   &nbs= p;            &= nbsp;      | CE2  |    | CE3&n= bsp; |
            &nb= sp;       +------+   &= nbsp;           &nbs= p;       +------+    &= #43;------+

In above figure,CE1 and CE2 are active= -active accessed to NVE1,NVE2 and NVE3,CE3 is active-active accessed to NVE= 2 and NVE3. CE1,CE2 and CE3 belongs to a VN.
NVE1,NVE2 and NVE3's IP addresses are 10.1.1.1,20.1.1.1 and 30.1.1.1 respec= tively.
When NVE1 receives multicast traffic from CE1, the NVE uses 10.1.1.1 as out= er tunnel source IP. When the traffic is injected to NVO3 network, NVE2 and= NVE3 should filter out the traffic to avoid the traffic loop back to CE1.<= br> But this forwarding principle will let CE3 can't receive the traffic.


To satisfy universal scenario, NVE edge group concept should be introduced,= each NVE has one IP address for a edge group. When multiple CEs attach to = the exact same set of NVEs, those NVEs can be considered as a single edge g= roup. An NVE can be in more than one edge group.

For example, in the above figure scenario, NVE1,NVE2 and NVE3 forms a ed= ge group, NVE2 and NVE3 forms a edge group.
A IP address can be configured or dynamically allocated for each edge group= , assuming the IP address for edge group 1 is 10.1.1.2, edge group 2 is 20.= 1.1.2.


When NVE1 receives multicast traffic from CE1 and injects it to NVO3 networ= k, 10.1.1.2 should be used as outer tunnel source IP, NVE2 and NVE3 relies = on the source IP to perform split-horizon filtering. NVE2 and NVE3 won't fo= rward the traffic to CE1 to avoid loop. If the port connecting to CE3 on NVE2 is DF port, NVE2 will forward = the traffic to CE3,NVE3 won't forward the traffic to CE3.

In summary, when each NVE recieves BUM traffic from local connecting CE,= the local forwarding principle on each NVE is as follows:
1. Local replication to non mc-lag ports(this is single homed ports).
2. Local replication to the ports associated with the same edge group,regar= dless of the DF Election state
3. Local replication to the mc-lag DF port associated with different edge g= roup. Do not replicate to mc-lag non-DF port associated with different edge= group.


Through this solution, IP address also can be greatly saved and can satisfy= all scenarios. If this solution is used, EVPN should be extended to suppor= t IP address dynamic allocation for each edge group to simplify service pro= visioning.

 

As for section 8.3.2, i have no doubts.

 

Thanks

Hi Auth= ors,

In draf= t-sd-l2vpn-evpn-overlay-03 draft, i think on the whole the process is clear= , but how to construct EVPN BGP routes is not detail described.
In EVPN network, MPLS Label is carried in Ethernet Auto-Discovery (A-D) rou= te,MAC/IP advertisement route,ESI Label Extended Community. In NVO3 network= , it is based on native IP, so all this MPLS Label should be replaced with = IP address. All process relies on MPLS label in EVPN should be modified to adapt to NVO3 network, such as sp= lit horizon, unicast traffic forwarding,load balancing and aliasing,and etc= .

So i ho= pe this draft had better provide more detail description about EVPN routes = format and corresponding procedures.

Jorge,
I would highly agree with your suggestion.=C2=A0

Even if for nothing else then point #3 is= a very reasonable and strong argument to be able to differentiate "de= fault MAC" from "unknown MAC":

3) the meaning o= f 00:..:00/48 is a bit different than only a default
route. We actually decided to call it =E2=80=9Cunknown mac route=E2=80=9D = since you might
want to advertise it from different gateway devices to attract all the
unknown traffic to ONLY those devices.

Thx,
R.

Hi Shunwan,

That=E2=80=99s a good point. A couple of comments about it and why I think = we

- I don=E2=80=99t know about draft-bonica, but there is already at least on= e
shipping implementation using 00:..:00/48 as per
draft-rabadan-l2vpn-dci-evpn-overlay
- There are a few reasons why we decided to use length 48:

1) The EVPN base draft only allows a MAC length =3D 48 and says other lengt= h
is out of scope
2) In the IP world, there is subneting so a default route with length /0 makes sense. In the MAC world, there is no subnetting (at least in real
implementations where MACs are not managed) so some implementations might have issues with lengths different than 48.
3) the meaning of 00:..:00/48 is a bit different than only a default
route. We actually decided to call it =E2=80=9Cunknown mac route=E2=80=9D s= ince you might

draft-rabadan-l2vpn-dci-evpn-overlay you can see that the ingress PE needs<= br> to send unknown traffic to all the egress PEs advertising the
unknown-mac-route, as opposed to only one.

Thank you.

I have got an answer that indeed the L2 frame in encapsulated, however I can find no reference to an RFC or details itself in this document where this is mentioned, to me therefore normal MPLS (RFC3031) applies and only the L3 packet is encapsulated. As this draft to my understanding proposes a replacement to VPLS I think it is necessary to mention or at least reference an RFC on how the entire L2 frame is to be encapsulated to avoid confusion. I would suggest a small part mentioning or referencing probably Pseudo Wires.

A couple of comments about it and why I = think we should use a length =3D 48. - I don=E2=80=99t know about draft-bonica, but there is already at least = one shipping implementation using 00:..:00/48 as per draft-rabadan-l2vpn-dci-evpn-overlay - There are a few reasons why we decided to use length 48: 1) The EVPN base draft only allows a MAC length =3D 48 and says other = length is out of scope 2) In the IP world, there is subneting so a default route with length /0 makes sense. In the MAC world, there is no subnetting (at least in real implementations where MACs are not managed) so some implementations = might have issues with lengths different than 48. 3) the meaning of 00:..:00/48 is a bit different than only a default route. We actually decided to call it =E2=80=9Cunknown mac = route=E2=80=9D since you might want to advertise it from different gateway devices to attract all the unknown traffic to ONLY those devices. In draft-rabadan-l2vpn-dci-evpn-overlay you can see that the ingress PE = needs to send unknown traffic to all the egress PEs advertising the unknown-mac-route, as opposed to only one. Thank you.

This draft is a work item of the Layer 2 Virtual Private Networks Working Group of the IETF. Title : BGP based Multi-homing in Virtual Private LAN Service Authors : Bhupesh Kothari Kireeti Kompella Wim Henderickx Florin Balus James Uttaro Senad Palislamovic Wen Lin Filename : draft-ietf-l2vpn-vpls-multihoming-07.txt Pages : 21 Date : 2014-07-03 Abstract: Virtual Private LAN Service (VPLS) is a Layer 2 Virtual Private Network (VPN) that gives its customers the appearance that their sites are connected via a Local Area Network (LAN). It is often required for the Service Provider (SP) to give the customer redundant connectivity to some sites, often called "multi-homing". This memo shows how BGP-based multi-homing can be offered in the context of LDP and BGP VPLS solutions. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-l2vpn-vpls-multihoming/ There's also a htmlized version available at: http://tools.ietf.org/html/draft-ietf-l2vpn-vpls-multihoming-07 A diff from the previous version is available at: http://www.ietf.org/rfcdiff?url2=draft-ietf-l2vpn-vpls-multihoming-07 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.

The word packet indicates L3. I think that we should be careful when using either packet or frame terminology to avoid confusion. One more point I find unclear, is the entire frame including FCS encapsulated or is the original FCS stripped and recalculated at the egress PE, as is done in Pseudo Wires? rfc 4888 p6: "The ingress Native Service Processing (NSP) function strips the preamble and frame check sequence (FCS) from the Ethernet frame and transports the frame in its entirety across the PW [..] The egress NSP function receives the Ethernet frame from the PW and regenerates the preamble or FCS before forwarding the frame" > Having said that, in the WG, we agreed to publish a evpn use-case draft > that could help clarify the main control plane and data plane concepts in > evpn: > http://tools.ietf.org/html/draft-rp-l2vpn-evpn-usage-02 > This draft contains many usages of the word packet, indicating L3, where the word frame in my opinion should be used. for example on page 13, point e: "e) The MPLS-encapsulated packet gets to PE2 and PE3. Since PE2 is non-DF for EVI1 on ESI12, and there is no other CE connected to PE2, the packet is discarded. At PE3, the packet is de-encapsulated, CE-VID translated if needed and replicated to CE3." The only indicator that I could find that indeed the entire frame is encapsulated is on page 26: "PE1 will push the MPLS Label(s) onto the original Ethernet frame and send the packet to the MPLS network" Again, I think that we should be careful when using either packet or frame terminology to avoid confusion. > > What I would suggest is to use that draft as a way to clarify all those > things so that the evpn researcher/implementer can use it as a reference. > If you agree, please go through it and suggest any additions.

Thank you for your openness, I realize that my comments may seem to be nitpicking, but I think this point should be made clear and it should not be assumed that L2 encapsulation is clear from the beginning. especially when EVPN is to be implemented as a replacement to VPLS rfc4761, rfc4762 which both state in their introduction the use of Pseudo Wires. > > Thanks. > Jorge > > -----Original Message----- > From: Stefan Plug > Date: Wednesday, July 2, 2014 at 4:55 AM > To: "l2vpn@ietf.org" > Subject: draft-ietf-l2vpn-evpn-07 L2 encapsulation?

Hi Authors of RFC 7117,

I have one doubt about the following d= escription in RFC 7117.

 

[description]: The best route procedur= es ensure that if multiple ASBRs, in an AS, receive the same Inter-AS A-D r= oute from their EBGP neighbors, only one of these ASBRs propagates this rou= te in Internal BGP (IBGP).

 

[weiguo]: How to coordinate differnent= ASBRs in an AS to ensure only one of the ASBRs propagates A-D routes to lo= cal AS in IBGP?
IMO, all ASBRs can propagate the A-D routes to remote PE in local AS, the r= emote PE pick one route as best route, the PE can only accept traffic data = from the ASBR that advertises the best route.

Hi John,

Can you give more explanation on the s= plit-horizon mechanism provided in section 5.1.3? I think a single IP addre= ss per NVE can't satisfy the split-horizon requiements in some scenarios. I= think at least one IP should be configured for each ESI. If multiple ESIs attached to same NVE group, one IP can be s= hared by these ESIs for split-horizon. Pls see my detail description in the= previous reply.

Thanks

weiguo

Hi John,

Thanks for your quick answer.

 

OK, section 5.1.3 describes how to con= struct  EVPN BGP Routes, the MPLS Label field in the MAC Advertisement= , Ethernet AD per EVI, and
Inclusive Multicast Ethernet Tag routes is used to carry the VNI or VSID.

 

As for section 8.3.1, split-horizon me= chanism relies on tracking other NVEs ip address, each ingress NVE only use= s a single IP address for split-horizon, as opposed to requiring an IP addr= ess per Ethernet
Segment per NVE.  I think a single IP address can't s= atisfy the requirements in the following scenario.
            &nb= sp;            =        +-----------+
            &nb= sp;            =        |   Router  |
            &nb= sp;            =        +-----------+

      &n= bsp;            = ;            &n= bsp; |     |    |
            &nb= sp;            -----= ---      |     --------
            &nb= sp;           | &nbs= p;            | = ;            |
            &nb= sp;         +------+ &= nbsp;    +-------+      = 3;------+
            &nb= sp;         |(NVE1) |  &n= bsp;  |(NVE2) |      | NVE3 |
            &nb= sp;         +------+ &= nbsp;    +-------+      = 3;------+
            &nb= sp;           * &nbs= p; |         *  |  ^ = ;       * |  ^
            &nb= sp;           * &nbs= p; |         *  |  ^^^^^^= ^^^^^^^^^^
            &nb= sp;           * &nbs= p; ----------*--------------*-|     ^
            &nb= sp;           ***********= ******************* |        ^
            &nb= sp;   MC-LAG1 *        &n= bsp;            = ; MC-LAG2 | MC-LAG3   ^
            &nb= sp;       +------+   &= nbsp;           &nbs= p;       +------+    &= #43;------+
            &nb= sp;       |  CE1 |   &nbs= p;            &= nbsp;      | CE2  |    | CE3&n= bsp; |
            &nb= sp;       +------+   &= nbsp;           &nbs= p;       +------+    &= #43;------+

In above figure,CE1 and CE2 are active= -active accessed to NVE1,NVE2 and NVE3,CE3 is active-active accessed to NVE= 2 and NVE3. CE1,CE2 and CE3 belongs to a VN.
NVE1,NVE2 and NVE3's IP addresses are 10.1.1.1,20.1.1.1 and 30.1.1.1 respec= tively.
When NVE1 receives multicast traffic from CE1, the NVE uses 10.1.1.1 as out= er tunnel source IP. When the traffic is injected to NVO3 network, NVE2 and= NVE3 should filter out the traffic to avoid the traffic loop back to CE1.<= br> But this forwarding principle will let CE3 can't receive the traffic.


To satisfy universal scenario, NVE edge group concept should be introduced,= each NVE has one IP address for a edge group. When multiple CEs attach to = the exact same set of NVEs, those NVEs can be considered as a single edge g= roup. An NVE can be in more than one edge group.

For example, in the above figure scenario, NVE1,NVE2 and NVE3 forms a ed= ge group, NVE2 and NVE3 forms a edge group.
A IP address can be configured or dynamically allocated for each edge group= , assuming the IP address for edge group 1 is 10.1.1.2, edge group 2 is 20.= 1.1.2.


When NVE1 receives multicast traffic from CE1 and injects it to NVO3 networ= k, 10.1.1.2 should be used as outer tunnel source IP, NVE2 and NVE3 relies = on the source IP to perform split-horizon filtering. NVE2 and NVE3 won't fo= rward the traffic to CE1 to avoid loop. If the port connecting to CE3 on NVE2 is DF port, NVE2 will forward = the traffic to CE3,NVE3 won't forward the traffic to CE3.

In summary, when each NVE recieves BUM traffic from local connecting CE,= the local forwarding principle on each NVE is as follows:
1. Local replication to non mc-lag ports(this is single homed ports).
2. Local replication to the ports associated with the same edge group,regar= dless of the DF Election state
3. Local replication to the mc-lag DF port associated with different edge g= roup. Do not replicate to mc-lag non-DF port associated with different edge= group.


Through this solution, IP address also can be greatly saved and can satisfy= all scenarios. If this solution is used, EVPN should be extended to suppor= t IP address dynamic allocation for each edge group to simplify service pro= visioning.

 

As for section 8.3.2, i have no doubts.

 

Thanks

weiguo

Hi Auth= ors,

In draf= t-sd-l2vpn-evpn-overlay-03 draft, i think on the whole the process is clear= , but how to construct EVPN BGP routes is not detail described.
In EVPN network, MPLS Label is carried in Ethernet Auto-Discovery (A-D) rou= te,MAC/IP advertisement route,ESI Label Extended Community. In NVO3 network= , it is based on native IP, so all this MPLS Label should be replaced with = IP address. All process relies on MPLS label in EVPN should be modified to adapt to NVO3 network, such as sp= lit horizon, unicast traffic forwarding,load balancing and aliasing,and etc= .

So i ho= pe this draft had better provide more detail description about EVPN routes = format and corresponding procedures.

Hi, Tissa:

There are many options for SFC OAM, BFD extension, Generic Header= extension, Generic TLV extension.

Unlike other existing OAM protocols, mechanisms and tools, SFC ne= ed to address OAM for the technology that is above layer 3.

SFC haven=A1=AFt developed OAM protocol yet at the top of layer 3= .

 

Before they developing OAM protocol, they need to figure out whet= her they need to develop technology dependent OAM protocol,

Or technology independent OAM protocol since SFC OAM and Overlay = OAM share a lot of similarities(e.g., both can use overlay technology to st= itch a set of overlay node or service node to form the end to end path). Why not build one protocol to support b= oth?

 

That=A1=AFs why we bring up transport independent OAM covering va= rious heterogeneous network technologies and propose to consolidate OAM in = both

Management plane and data plane.

http://tools.ietf.org/html/draft= -ww-opsawg-multi-layer-oam-02

http://tools= .ietf.org/html/draft-king-opsawg-time-multi-layer-oam-use-case-01.txt

 

Regarding flow-entropy, why not reuse entropy mechanisms in the e= xisting underlying transport. How is flow entropy different from ECMP choic= e you proposed in the draft.

If my understanding is correct, IEEE 802.1ag only support Equal C= ost Tree (ECT) mechanism instead of ECMP, IEEE802.1Qbp support ECMP,

Are you proposing to combine ECT supported by IEEE 802.1ag with E= CMP supported by IEEE 802.1Qbp and use them together at the same time in th= e same network?

 

Also BFD and IEEE 802.1ag CFM share a lot of commonality, e.g., C= CM-interval, BFD interval. If we integrate them together, we really need to= think about how to integrate them together in the management plane. Is there any common component we can define for b= oth? How we define these component and make them more extensible.

 

Regards!

=D6=F7=CC=E2: RE: YANG models for OAM

 

Hi Qin<= o:p>

&n= bsp;

There a= re several way this is applicable to SFC

&n= bsp;

= 1.       SFC is underlayer independent , which means it can have all sorts of encap= types underneath, the model presented in tissa-netmod-oam, address exactly= that issue. Instead of re-inventing and re-implementing various different OAM the draft propose to integrate t= hem at the management layer.

= 2.       In this draft we define a flow-entropy as an opaque element that each of t= he technology type can specify and include. If we look at draft-quinn-sfc-n= sh-02.txt, it define a block that specifies SFC. SFC version of YANG  can specify this as part of its flow entrop= y. The beauty is that it is all up to the technology to specify that (size = and shape is technology dependent) and base model is still intact.

&n= bsp;

With th= e above in mind , can you please review draft-tissa-netmod-oam and see it i= s flexible and extensible enough to for the purpose. If things are missing = we can add and extend.

&n= bsp;

I have = requested netmod WG chairs for a presentation slot for further discussion o= f the draft.

Hi, Tissa:

Thanks for initiating discussion on this topic.=

Unified OAM for multi-Layer network is a good idea to me.

draft-ww-opsawg-multi-layer-oam-00 we proposed in opsawg laid out= the an initial description of the problem.

The question to draft-= tissa-netmod-oam is

I am wondering how this generic Yang Model can be applied to SFC = environment?

How do you support the case where two endpoints support different= layer OAM or doesn=A1=AFt support any OAM at that layer.=

 

BTW: I have cc=A1=AFed time mailing list since I believe this mai= ling list is purposed to look for generic and integrated OAM covering vario= us heterogeneous networking technologies.

Regards!

Hi John,

Can you give more explanation on the split-horizon mechanism pro= vided in section 5.1.3? I think a single IP address per NVE can't satisfy t= he split-horizon requiements in some scenarios. I think at least one IP should be configured for each ESI. If multiple ESIs attach= ed to same NVE group, one IP can be shared by these ESIs for split-horizon.= Pls see my detail description in the previous reply.

Thanks

Hi John,

Thanks for your quick answer.

 

OK, section 5.1.3 describes how to construct  EVPN BGP Rout= es, the MPLS Label field in the MAC Advertisement, Ethernet AD per EVI, and=
Inclusive Multicast Ethernet Tag routes is used to carry the VNI or VSID.

 

As for section 8.3.1, split-horizon mechanism relies on tracking= other NVEs ip address, each ingress NVE only uses a single IP address for = split-horizon, as opposed to requiring an IP address per Ethernet
Segment per NVE.  I think a single IP = address can't satisfy the requirements in the following scenario.
            &nb= sp;            =        +-----------+
            &nb= sp;            =        |   Router  |
            &nb= sp;            =        +-----------+

          &nbs= p;            &= nbsp;         |   &n= bsp; |    |
            &nb= sp;            -----= ---      |     --------
            &nb= sp;           | &nbs= p;            | = ;            |
            &nb= sp;         +------+ &= nbsp;    +-------+      = 3;------+
            &nb= sp;         |(NVE1) |  &n= bsp;  |(NVE2) |      | NVE3 |
            &nb= sp;         +------+ &= nbsp;    +-------+      = 3;------+
            &nb= sp;           * &nbs= p; |         *  |  ^ = ;       * |  ^
            &nb= sp;           * &nbs= p; |         *  |  ^^^^^^= ^^^^^^^^^^
            &nb= sp;           * &nbs= p; ----------*--------------*-|     ^
            &nb= sp;           ***********= ******************* |        ^
            &nb= sp;   MC-LAG1 *        &n= bsp;            = ; MC-LAG2 | MC-LAG3   ^
            &nb= sp;       +------+   &= nbsp;           &nbs= p;       +------+    &= #43;------+
            &nb= sp;       |  CE1 |   &nbs= p;            &= nbsp;      | CE2  |    | CE3&n= bsp; |
            &nb= sp;       +------+   &= nbsp;           &nbs= p;       +------+    &= #43;------+

In above figure,CE1 and CE2 are active-active accessed to NVE1,N= VE2 and NVE3,CE3 is active-active accessed to NVE2 and NVE3. CE1,CE2 and CE= 3 belongs to a VN.
NVE1,NVE2 and NVE3's IP addresses are 10.1.1.1,20.1.1.1 and 30.1.1.1 respec= tively.
When NVE1 receives multicast traffic from CE1, the NVE uses 10.1.1.1 as out= er tunnel source IP. When the traffic is injected to NVO3 network, NVE2 and= NVE3 should filter out the traffic to avoid the traffic loop back to CE1.<= br> But this forwarding principle will let CE3 can't receive the traffic.


To satisfy universal scenario, NVE edge group concept should be introduced,= each NVE has one IP address for a edge group. When multiple CEs attach to = the exact same set of NVEs, those NVEs can be considered as a single edge g= roup. An NVE can be in more than one edge group.

For example, in the above figure scenario, NVE1,NVE2 and NVE3 fo= rms a edge group, NVE2 and NVE3 forms a edge group.
A IP address can be configured or dynamically allocated for each edge group= , assuming the IP address for edge group 1 is 10.1.1.2, edge group 2 is 20.= 1.1.2.


When NVE1 receives multicast traffic from CE1 and injects it to NVO3 networ= k, 10.1.1.2 should be used as outer tunnel source IP, NVE2 and NVE3 relies = on the source IP to perform split-horizon filtering. NVE2 and NVE3 won't fo= rward the traffic to CE1 to avoid loop. If the port connecting to CE3 on NVE2 is DF port, NVE2 will forward = the traffic to CE3,NVE3 won't forward the traffic to CE3.=

In summary, when each NVE recieves BUM traffic from local connec= ting CE, the local forwarding principle on each NVE is as follows:
1. Local replication to non mc-lag ports(this is single homed ports).
2. Local replication to the ports associated with the same edge group,regar= dless of the DF Election state
3. Local replication to the mc-lag DF port associated with different edge g= roup. Do not replicate to mc-lag non-DF port associated with different edge= group.


Through this solution, IP address also can be greatly saved and can satisfy= all scenarios. If this solution is used, EVPN should be extended to suppor= t IP address dynamic allocation for each edge group to simplify service pro= visioning.

 

As for section 8.3.2, i have no doubts.

 

Thanks

Hi Authors,

In draft-sd-l2vpn-evpn-overlay-03 draft, i think on the whole the= process is clear, but how to construct EVPN BGP routes is not detail descr= ibed.
In EVPN network, MPLS Label is carried in Ethernet Auto-Discovery (A-D) rou= te,MAC/IP advertisement route,ESI Label Extended Community. In NVO3 network= , it is based on native IP, so all this MPLS Label should be replaced with = IP address. All process relies on MPLS label in EVPN should be modified to adapt to NVO3 network, such as sp= lit horizon, unicast traffic forwarding,load balancing and aliasing,and etc= .

So i hope this draft had better provide more detail description a= bout EVPN routes format and corresponding procedures.

Thanks

Hi Qin

 

May be a point is miss= ed here.

 

1.&n= bsp;     Thought SFC ca= n go up and down on layers, what controls that behavior ? Is=A1=AFnt it the= Service header ?

2.&n= bsp;     Is the OAM com= es down to fault isolation, verification , monitoring etc for the specified= SH ?

 

Like discussed before = (many times) exact en-cap is less important what is important is to have a = model that define OAM framework and scope. CFM to my opinion do an excellen= t job in defining what is needed. Hence the choice of a similar model for the YANG Model.

 

You have noted BFD and= CFM are similar because they have similar set of timers. That is a wrong c= omparison. Have similar set of timers does not make two protocols the same.= What makes them is what framework they follows.  We have used key word CFM here loosely. Though we borrow lo= ts of concepts form CFM there are things that needed to be revisited.<= /o:p>

 

I have requested prese= ntation slots in nvo3 and NETMOD working groups and will be going through i= n details how each one of the technologies map to YANG model presented here= .

Subject: RE: YANG models for OAM

 

Hi, T= issa:

There= are many options for SFC OAM, BFD extension, Generic Header extension, Gen= eric TLV extension.

Unlik= e other existing OAM protocols, mechanisms and tools, SFC need to address O= AM for the technology that is above layer 3.

SFC h= aven=A1=AFt developed OAM protocol yet at the top of layer 3.

=  

Befor= e they developing OAM protocol, they need to figure out whether they need t= o develop technology dependent OAM protocol,

Or te= chnology independent OAM protocol since SFC OAM and Overlay OAM share a lot= of similarities(e.g., both can use overlay technology to stitch a set of o= verlay node or service node to form the end to end path). Why not build one protocol to support both?

=  

That= =A1=AFs why we bring up transport independent OAM covering various heteroge= neous network technologies and propose to consolidate OAM in both

Manag= ement plane and data plane.

http://tools.ietf.org/html/draft-= king-opsawg-time-multi-layer-oam-use-case-01.txt

=  

Regar= ding flow-entropy, why not reuse entropy mechanisms in the existing underly= ing transport. How is flow entropy different from ECMP choice you proposed = in the draft.

If my= understanding is correct, IEEE 802.1ag only support Equal Cost Tree (ECT) = mechanism instead of ECMP, IEEE802.1Qbp support ECMP,

Are y= ou proposing to combine ECT supported by IEEE 802.1ag with ECMP supported b= y IEEE 802.1Qbp and use them together at the same time in the same network?=

=  

Also = BFD and IEEE 802.1ag CFM share a lot of commonality, e.g., CCM-interval, BF= D interval. If we integrate them together, we really need to think about ho= w to integrate them together in the management plane. Is there any common component we can define for both? Ho= w we define these component and make them more extensible.

=D6=F7=CC=E2: RE: YANG models for OAM

 

Hi Qin

 

There are several way = this is applicable to SFC

 

1.&n= bsp;     SFC is underla= yer independent , which means it can have all sorts of encap types undernea= th, the model presented in tissa-netmod-oam, address exactly that issue. In= stead of re-inventing and re-implementing various different OAM the draft propose to integrate them at the managemen= t layer.

2.&n= bsp;     In this draft = we define a flow-entropy as an opaque element that each of the technology t= ype can specify and include. If we look at draft-quinn-sfc-nsh-02.txt, it d= efine a block that specifies SFC. SFC version of YANG  can specify this as part of its flow entropy. Th= e beauty is that it is all up to the technology to specify that (size and s= hape is technology dependent) and base model is still intact.

 

With the above in mind= , can you please review draft-tissa-netmod-oam and see it is flexible and = extensible enough to for the purpose. If things are missing we can add and = extend.

 

I have requested netmo= d WG chairs for a presentation slot for further discussion of the draft. &n= bsp;

Hi, T= issa:

Thank= s for initiating discussion on this topic.

Unifi= ed OAM for multi-Layer network is a good idea to me.

draft= -ww-opsawg-multi-layer-oam-00 we proposed in opsawg laid out the an initial= description of the problem.

The q= uestion to draft-tissa-netmod-oam is

I am = wondering how this generic Yang Model can be applied to SFC environment?

How d= o you support the case where two endpoints support different layer OAM or d= oesn=A1=AFt support any OAM at that layer.

=  

BTW: = I have cc=A1=AFed time mailing list since I believe this mailing list is pu= rposed to look for generic and integrated OAM covering various heterogeneou= s networking technologies.

Hi Qin

 

May be a point is miss= ed here.

 

1.&n= bsp;     Thought SFC ca= n go up and down on layers, what controls that behavior ? Is=A1=AFnt it the= Service header ?

2.&n= bsp;     Is the OAM com= es down to fault isolation, verification , monitoring etc for the specified= SH ?

 

Like discussed before = (many times) exact en-cap is less important what is important is to have a = model that define OAM framework and scope. CFM to my opinion do an excellen= t job in defining what is needed. Hence the choice of a similar model for the YANG Model.

 

You have noted BFD and= CFM are similar because they have similar set of timers. That is a wrong c= omparison. Have similar set of timers does not make two protocols the same.= What makes them is what framework they follows.  We have used key word CFM here loosely. Though we borrow lo= ts of concepts form CFM there are things that needed to be revisited.<= /o:p>

 

I have requested prese= ntation slots in nvo3 and NETMOD working groups and will be going through i= n details how each one of the technologies map to YANG model presented here= .

Hi, T= issa:

There= are many options for SFC OAM, BFD extension, Generic Header extension, Gen= eric TLV extension.

Unlik= e other existing OAM protocols, mechanisms and tools, SFC need to address O= AM for the technology that is above layer 3.

SFC h= aven=A1=AFt developed OAM protocol yet at the top of layer 3.

=  

Befor= e they developing OAM protocol, they need to figure out whether they need t= o develop technology dependent OAM protocol,

Or te= chnology independent OAM protocol since SFC OAM and Overlay OAM share a lot= of similarities(e.g., both can use overlay technology to stitch a set of o= verlay node or service node to form the end to end path). Why not build one protocol to support both?

=  

That= =A1=AFs why we bring up transport independent OAM covering various heteroge= neous network technologies and propose to consolidate OAM in both

Manag= ement plane and data plane.

http://tools.ietf.org/html/draft-ww-opsawg-multi-laye= r-oam-02

http://tools.ietf.org/html/draft-= king-opsawg-time-multi-layer-oam-use-case-01.txt

=  

Regar= ding flow-entropy, why not reuse entropy mechanisms in the existing underly= ing transport. How is flow entropy different from ECMP choice you proposed = in the draft.

If my= understanding is correct, IEEE 802.1ag only support Equal Cost Tree (ECT) = mechanism instead of ECMP, IEEE802.1Qbp support ECMP,

Are y= ou proposing to combine ECT supported by IEEE 802.1ag with ECMP supported b= y IEEE 802.1Qbp and use them together at the same time in the same network?=

=  

Also = BFD and IEEE 802.1ag CFM share a lot of commonality, e.g., CCM-interval, BF= D interval. If we integrate them together, we really need to think about ho= w to integrate them together in the management plane. Is there any common component we can define for both? Ho= w we define these component and make them more extensible.

=D6=F7=CC=E2: RE: YANG models for OAM

 

Hi Qin

 

There are several way = this is applicable to SFC

 

1.&n= bsp;     SFC is underla= yer independent , which means it can have all sorts of encap types undernea= th, the model presented in tissa-netmod-oam, address exactly that issue. In= stead of re-inventing and re-implementing various different OAM the draft propose to integrate them at the managemen= t layer.

2.&n= bsp;     In this draft = we define a flow-entropy as an opaque element that each of the technology t= ype can specify and include. If we look at draft-quinn-sfc-nsh-02.txt, it d= efine a block that specifies SFC. SFC version of YANG  can specify this as part of its flow entropy. Th= e beauty is that it is all up to the technology to specify that (size and s= hape is technology dependent) and base model is still intact.

 

With the above in mind= , can you please review draft-tissa-netmod-oam and see it is flexible and = extensible enough to for the purpose. If things are missing we can add and = extend.

 

I have requested netmo= d WG chairs for a presentation slot for further discussion of the draft. &n= bsp;

Hi, T= issa:

Thank= s for initiating discussion on this topic.

Unifi= ed OAM for multi-Layer network is a good idea to me.

draft= -ww-opsawg-multi-layer-oam-00 we proposed in opsawg laid out the an initial= description of the problem.

The q= uestion to draft-tissa-netmod-oam is

I am = wondering how this generic Yang Model can be applied to SFC environment?

How d= o you support the case where two endpoints support different layer OAM or d= oesn=A1=AFt support any OAM at that layer.

=  

BTW: = I have cc=A1=AFed time mailing list since I believe this mailing list is pu= rposed to look for generic and integrated OAM covering various heterogeneou= s networking technologies.

Hi, Tissa:

I don=A1=AFt think the idea you proposed have any inconsistency w= ith what we are proposing in draft-ww-opsawg-multi-layer-oam-02. But looks = like we are debating something,J

You and us are both looking for OAM consolidation in the manageme= nt, in addition, we are looking for OAM consolidation in the data plane.

Please see my reply inline below.

 

Regards!

=D6=F7=CC=E2: RE: YANG models for OAM

 

Hi Qin<= o:p>

&n= bsp;

May be = a point is missed here.

&n= bsp;

= 1.       Thought SFC can go up and down on layers, what controls that behavior ? Is= =A1=AFnt it the Service header ?

[Qin]: It is possible, but who control that behavior, it is the m= anagement plane, the management plane need to interact with different layer= OAM in the data plane or

Management plane need to interact with OAM protocol that is defin= ed for SFC at the top of layer 3.

 

= 2.       Is the OAM comes down to fault isolation, verification , monitoring etc fo= r the specified SH ?

[Qin]: = Not clear whether SH is the only approach. OAM information can be put into = BDF protocol or Generic TLV as well.

 

Like di= scussed before (many times) exact en-cap is less important what is importan= t is to have a model that define OAM framework and scope. CFM to my opinion= do an excellent job in defining what is needed. Hence the choice of a similar model for the YANG Model.

 

[Qin]: We are on the same page, but isn=A1=AFt more straightforwa= rd and reasonable to define Generic OAM framework separated from Yang Data = model for Generic OAM.

That=A1=AFs what we like to propose in the draft-ww-opsawg-multi-= layer-oam-02. Developing separate Architecture and Framework from Transport= Independent OAM Problem statement draft.

Generic OAM framework should also allow more interaction between = data plane and management plane and more interworking between different lay= er OAM protocol.

&n= bsp;

You hav= e noted BFD and CFM are similar because they have similar set of timers. Th= at is a wrong comparison. Have similar set of timers does not make two prot= ocols the same.

 

[Qin]: That=A1=AFs not what we are proposing, we hope in the mana= gement plane there is some common components or elements that can be used b= y not only BFD, but also CFM.

[Qin]: That would be a very good survey, in my opinion, before go= ing there, isn=A1=AFt more nice to have a gap analysis document to

a .Identify technology dependent and independent component

b.  analyze and understand the different motivations and opp= ortunities for optimisation of OAM in different technology networks,

and the trade-offs between those optimisations and the overall ad= vantage of a generic OAM mechanism.

Hi, Tissa:

There are many options for SFC OAM, BFD extension, Generic Header= extension, Generic TLV extension.

Unlike other existing OAM protocols, mechanisms and tools, SFC ne= ed to address OAM for the technology that is above layer 3.

SFC haven=A1=AFt developed OAM protocol yet at the top of layer 3= .

 

Before they developing OAM protocol, they need to figure out whet= her they need to develop technology dependent OAM protocol,

Or technology independent OAM protocol since SFC OAM and Overlay = OAM share a lot of similarities(e.g., both can use overlay technology to st= itch a set of overlay node or service node to form the end to end path). Why not build one protocol to support b= oth?

 

That=A1=AFs why we bring up transport independent OAM covering va= rious heterogeneous network technologies and propose to consolidate OAM in = both

Management plane and data plane.

http://tools.ietf.org/html/draft= -ww-opsawg-multi-layer-oam-02

http://tools= .ietf.org/html/draft-king-opsawg-time-multi-layer-oam-use-case-01.txt

 

Regarding flow-entropy, why not reuse entropy mechanisms in the e= xisting underlying transport. How is flow entropy different from ECMP choic= e you proposed in the draft.

If my understanding is correct, IEEE 802.1ag only support Equal C= ost Tree (ECT) mechanism instead of ECMP, IEEE802.1Qbp support ECMP,

Are you proposing to combine ECT supported by IEEE 802.1ag with E= CMP supported by IEEE 802.1Qbp and use them together at the same time in th= e same network?

 

Also BFD and IEEE 802.1ag CFM share a lot of commonality, e.g., C= CM-interval, BFD interval. If we integrate them together, we really need to= think about how to integrate them together in the management plane. Is there any common component we can define for b= oth? How we define these component and make them more extensible.

 

Regards!

=D6=F7=CC=E2: RE: YANG models for OAM

 

Hi Qin<= o:p>

&n= bsp;

There a= re several way this is applicable to SFC

&n= bsp;

= 1.       SFC is underlayer independent , which means it can have all sorts of encap= types underneath, the model presented in tissa-netmod-oam, address exactly= that issue. Instead of re-inventing and re-implementing various different OAM the draft propose to integrate t= hem at the management layer.

= 2.       In this draft we define a flow-entropy as an opaque element that each of t= he technology type can specify and include. If we look at draft-quinn-sfc-n= sh-02.txt, it define a block that specifies SFC. SFC version of YANG  can specify this as part of its flow entrop= y. The beauty is that it is all up to the technology to specify that (size = and shape is technology dependent) and base model is still intact.

&n= bsp;

With th= e above in mind , can you please review draft-tissa-netmod-oam and see it i= s flexible and extensible enough to for the purpose. If things are missing = we can add and extend.

&n= bsp;

I have = requested netmod WG chairs for a presentation slot for further discussion o= f the draft.

Hi, Tissa:

Thanks for initiating discussion on this topic.=

Unified OAM for multi-Layer network is a good idea to me.

draft-ww-opsawg-multi-layer-oam-00 we proposed in opsawg laid out= the an initial description of the problem.

The question to draft-= tissa-netmod-oam is

I am wondering how this generic Yang Model can be applied to SFC = environment?

How do you support the case where two endpoints support different= layer OAM or doesn=A1=AFt support any OAM at that layer.=

 

BTW: I have cc=A1=AFed time mailing list since I believe this mai= ling list is purposed to look for generic and integrated OAM covering vario= us heterogeneous networking technologies.

Regards!

Hi John,

Thank you very much.

You are right. Local bias on ingress N= VE and  tracking other NVEs IP on egress PE provide complete= d split-horizon filtering solution in NVO3 network. Local bias is different= from split-horizon filtering mechanism in EVPN base protocol.

Thanks

Weiguo,

 

With local bias, an ingress PE sends a cop= y of a BUM packet received from a CE to every ES to which it is attached, r= egardless of whether it is the DF for a given ES.  An egress PE sends a copy of a BUM received from an ingr= ess PE to every ES for which it is the DF, except for those ESes which it h= as in common with the ingress PE.

 

Yours Irrespectively,

 

John

Hi Joh= n,

Can yo= u give more explanation on the split-horizon mechanism provided in section = 5.1.3? I think a single IP address per NVE can't satisfy the split-horizon = requiements in some scenarios. I think at least one IP should be configured for each ESI. If multiple ESIs attach= ed to same NVE group, one IP can be shared by these ESIs for split-horizon.= Pls see my detail description in the previous reply.<= /p>

Hi Joh= n,

Thanks= for your quick answer.

 

OK, se= ction 5.1.3 describes how to construct  EVPN BGP Routes, the MPLS Labe= l field in the MAC Advertisement, Ethernet AD per EVI, and
Inclusive Multicast Ethernet Tag routes is used to carry the VNI or VSID.

 

As for= section 8.3.1, split-horizon mechanism relies on tracking other NVEs ip ad= dress, each ingress NVE only uses a single IP address for split-horizon, as= opposed to requiring an IP address per Ethernet
Segment per NVE.  I think a single IP address can't s= atisfy the requirements in the following scenario.
            &nb= sp;            =        +-----------+
            &nb= sp;            =        |   Router  |
            &nb= sp;            =        +-----------+

 =             &nb= sp;            =        |     |  = ;  |
            &nb= sp;            -----= ---      |     --------
            &nb= sp;           | &nbs= p;            | = ;            |
            &nb= sp;         +------+ &= nbsp;    +-------+      = 3;------+
            &nb= sp;         |(NVE1) |  &n= bsp;  |(NVE2) |      | NVE3 |
            &nb= sp;         +------+ &= nbsp;    +-------+      = 3;------+
            &nb= sp;           * &nbs= p; |         *  |  ^ = ;       * |  ^
            &nb= sp;           * &nbs= p; |         *  |  ^^^^^^= ^^^^^^^^^^
            &nb= sp;           * &nbs= p; ----------*--------------*-|     ^
            &nb= sp;           ***********= ******************* |        ^
            &nb= sp;   MC-LAG1 *        &n= bsp;            = ; MC-LAG2 | MC-LAG3   ^
            &nb= sp;       +------+   &= nbsp;           &nbs= p;       +------+    &= #43;------+
            &nb= sp;       |  CE1 |   &nbs= p;            &= nbsp;      | CE2  |    | CE3&n= bsp; |
            &nb= sp;       +------+   &= nbsp;           &nbs= p;       +------+    &= #43;------+

In abo= ve figure,CE1 and CE2 are active-active accessed to NVE1,NVE2 and NVE3,CE3 = is active-active accessed to NVE2 and NVE3. CE1,CE2 and CE3 belongs to a VN= .
NVE1,NVE2 and NVE3's IP addresses are 10.1.1.1,20.1.1.1 and 30.1.1.1 respec= tively.
When NVE1 receives multicast traffic from CE1, the NVE uses 10.1.1.1 as out= er tunnel source IP. When the traffic is injected to NVO3 network, NVE2 and= NVE3 should filter out the traffic to avoid the traffic loop back to CE1.<= br> But this forwarding principle will let CE3 can't receive the traffic.


To satisfy universal scenario, NVE edge group concept should be introduced,= each NVE has one IP address for a edge group. When multiple CEs attach to = the exact same set of NVEs, those NVEs can be considered as a single edge g= roup. An NVE can be in more than one edge group.

For ex= ample, in the above figure scenario, NVE1,NVE2 and NVE3 forms a edge group,= NVE2 and NVE3 forms a edge group.
A IP address can be configured or dynamically allocated for each edge group= , assuming the IP address for edge group 1 is 10.1.1.2, edge group 2 is 20.= 1.1.2.


When NVE1 receives multicast traffic from CE1 and injects it to NVO3 networ= k, 10.1.1.2 should be used as outer tunnel source IP, NVE2 and NVE3 relies = on the source IP to perform split-horizon filtering. NVE2 and NVE3 won't fo= rward the traffic to CE1 to avoid loop. If the port connecting to CE3 on NVE2 is DF port, NVE2 will forward = the traffic to CE3,NVE3 won't forward the traffic to CE3.

In sum= mary, when each NVE recieves BUM traffic from local connecting CE, the loca= l forwarding principle on each NVE is as follows:
1. Local replication to non mc-lag ports(this is single homed ports).
2. Local replication to the ports associated with the same edge group,regar= dless of the DF Election state
3. Local replication to the mc-lag DF port associated with different edge g= roup. Do not replicate to mc-lag non-DF port associated with different edge= group.


Through this solution, IP address also can be greatly saved and can satisfy= all scenarios. If this solution is used, EVPN should be extended to suppor= t IP address dynamic allocation for each edge group to simplify service pro= visioning.

 

As for= section 8.3.2, i have no doubts.

Hi Auth= ors,

In draf= t-sd-l2vpn-evpn-overlay-03 draft, i think on the whole the process is clear= , but how to construct EVPN BGP routes is not detail described.
In EVPN network, MPLS Label is carried in Ethernet Auto-Discovery (A-D) rou= te,MAC/IP advertisement route,ESI Label Extended Community. In NVO3 network= , it is based on native IP, so all this MPLS Label should be replaced with = IP address. All process relies on MPLS label in EVPN should be modified to adapt to NVO3 network, such as sp= lit horizon, unicast traffic forwarding,load balancing and aliasing,and etc= .So i ho= pe this draft had better provide more detail description about EVPN routes = format and corresponding procedures.

Hi John,

Thank you very much.

You are right. Local bias on ingress NVE and  tra= cking other NVEs IP on egress PE provide completed split-horizon filtering = solution in NVO3 network. Local bias is different from split-horizon filtering mechanism in EVPN base protocol.

 

[JD]  = ;This is why the draft advises that the PEs attached to a given ES all use = the same encapsulation.

Weiguo,

With local bias, an ingre= ss PE sends a copy of a BUM packet received from a CE to every ES to which = it is attached, regardless of whether it is the DF for a given ES.  An egress PE sends a copy of a BUM received from an ingres= s PE to every ES for which it is the DF, except for those ESes which it has= in common with the ingress PE.

Hi John,

Can you give more explanation on the split-horizon mechanism pro= vided in section 5.1.3? I think a single IP address per NVE can't satisfy t= he split-horizon requiements in some scenarios. I think at least one IP should be configured for each ESI. If multiple ESIs attach= ed to same NVE group, one IP can be shared by these ESIs for split-horizon.= Pls see my detail description in the previous reply.

Thanks

Hi John,

Thanks for your quick answer.

 

OK, section 5.1.3 describes how to construct  EVPN BGP Rout= es, the MPLS Label field in the MAC Advertisement, Ethernet AD per EVI, and=
Inclusive Multicast Ethernet Tag routes is used to carry the VNI or VSID.

 

As for section 8.3.1, split-horizon mechanism relies on tracking= other NVEs ip address, each ingress NVE only uses a single IP address for = split-horizon, as opposed to requiring an IP address per Ethernet
Segment per NVE.  I think a single IP = address can't satisfy the requirements in the following scenario.
            &nb= sp;            =        +-----------+
            &nb= sp;            =        |   Router  |
            &nb= sp;            =        +-----------+

          &nbs= p;            &= nbsp;         |   &n= bsp; |    |
            &nb= sp;            -----= ---      |     --------
            &nb= sp;           | &nbs= p;            | = ;            |
            &nb= sp;         +------+ &= nbsp;    +-------+      = 3;------+
            &nb= sp;         |(NVE1) |  &n= bsp;  |(NVE2) |      | NVE3 |
            &nb= sp;         +------+ &= nbsp;    +-------+      = 3;------+
            &nb= sp;           * &nbs= p; |         *  |  ^ = ;       * |  ^
            &nb= sp;           * &nbs= p; |         *  |  ^^^^^^= ^^^^^^^^^^
            &nb= sp;           * &nbs= p; ----------*--------------*-|     ^
            &nb= sp;           ***********= ******************* |        ^
            &nb= sp;   MC-LAG1 *        &n= bsp;            = ; MC-LAG2 | MC-LAG3   ^
            &nb= sp;       +------+   &= nbsp;           &nbs= p;       +------+    &= #43;------+
            &nb= sp;       |  CE1 |   &nbs= p;            &= nbsp;      | CE2  |    | CE3&n= bsp; |
            &nb= sp;       +------+   &= nbsp;           &nbs= p;       +------+    &= #43;------+

In above figure,CE1 and CE2 are active-active accessed to NVE1,N= VE2 and NVE3,CE3 is active-active accessed to NVE2 and NVE3. CE1,CE2 and CE= 3 belongs to a VN.
NVE1,NVE2 and NVE3's IP addresses are 10.1.1.1,20.1.1.1 and 30.1.1.1 respec= tively.
When NVE1 receives multicast traffic from CE1, the NVE uses 10.1.1.1 as out= er tunnel source IP. When the traffic is injected to NVO3 network, NVE2 and= NVE3 should filter out the traffic to avoid the traffic loop back to CE1.<= br> But this forwarding principle will let CE3 can't receive the traffic.


To satisfy universal scenario, NVE edge group concept should be introduced,= each NVE has one IP address for a edge group. When multiple CEs attach to = the exact same set of NVEs, those NVEs can be considered as a single edge g= roup. An NVE can be in more than one edge group.

For example, in the above figure scenario, NVE1,NVE2 and NVE3 fo= rms a edge group, NVE2 and NVE3 forms a edge group.
A IP address can be configured or dynamically allocated for each edge group= , assuming the IP address for edge group 1 is 10.1.1.2, edge group 2 is 20.= 1.1.2.


When NVE1 receives multicast traffic from CE1 and injects it to NVO3 networ= k, 10.1.1.2 should be used as outer tunnel source IP, NVE2 and NVE3 relies = on the source IP to perform split-horizon filtering. NVE2 and NVE3 won't fo= rward the traffic to CE1 to avoid loop. If the port connecting to CE3 on NVE2 is DF port, NVE2 will forward = the traffic to CE3,NVE3 won't forward the traffic to CE3.=

In summary, when each NVE recieves BUM traffic from local connec= ting CE, the local forwarding principle on each NVE is as follows:
1. Local replication to non mc-lag ports(this is single homed ports).
2. Local replication to the ports associated with the same edge group,regar= dless of the DF Election state
3. Local replication to the mc-lag DF port associated with different edge g= roup. Do not replicate to mc-lag non-DF port associated with different edge= group.


Through this solution, IP address also can be greatly saved and can satisfy= all scenarios. If this solution is used, EVPN should be extended to suppor= t IP address dynamic allocation for each edge group to simplify service pro= visioning.

 

As for section 8.3.2, i have no doubts.

 

Thanks

Hi Authors,

In draft-sd-l2vpn-evpn-overlay-03 draft, i think on the whole the= process is clear, but how to construct EVPN BGP routes is not detail descr= ibed.
In EVPN network, MPLS Label is carried in Ethernet Auto-Discovery (A-D) rou= te,MAC/IP advertisement route,ESI Label Extended Community. In NVO3 network= , it is based on native IP, so all this MPLS Label should be replaced with = IP address. All process relies on MPLS label in EVPN should be modified to adapt to NVO3 network, such as sp= lit horizon, unicast traffic forwarding,load balancing and aliasing,and etc= .

So i hope this draft had better provide more detail description a= bout EVPN routes format and corresponding procedures.

Thanks

Th= e Routing Directorate seeks to review all routing or routing-related drafts= as they pass through IETF last call and IESG review, and sometimes on spec= ial request. The purpose of the review is to provide assistance to the Rout= ing ADs. For more information about the Routing Directorate, please see htt= p://trac.tools.ietf.org/area/rtg/trac/wiki/RtgDir Although these comments are primarily for the use of the Routing ADs, it wo= uld be helpful if you could consider them along with any other IETF Last Ca= ll comments that you receive, and strive to resolve them through discussion= or by updating the draft.

=A1=AD

5 Operational Models for = Symmetric Inter-Subnet Forwarding

 

   The following = sections describe several main symmetric IRB = forwarding

   its TSes with = the following field set:

 

   - RD and ESI per = [EVPN]

   - Ethernet Tag = =3D 0; assuming VLAN-based service

   - MAC Address = Length =3D 48

   - MAC Address = =3D Mi ; where i =3D 1,2,3,4, or 5 in the above = example

[Vincent]: = According to my understanding of the symmetric IRB Solution=A3=ACno = need to advertise the MAC Addresses of the TSes? I understand = aright?

   - IP Address = Length =3D 32 or 128

   - IP Address =3D = IPi ; where i =3D 1,2,3,4, or 5 in the above = example

   - Label-1 =3D = MPLS Label or VNID corresponding to EVI

   -  The = packet is then encapsulated with the proper header based = on

   the above info. = The inner MAC SA and VTEP SA is set to NVE's MAC = and

   identify the = IP-VRF table and then performs an IP lookup = which

   results in = destination TS (TS3) MAC address and the access-facing = IRB

   interface over = which the packet needs to be sent.

 

   - The IP packet = is encapsulated with an Ethernet header with MAC = SA

   set to that of = NVE-2 MAC address(MACy) and MAC DA set to that = of

   destination TS = (TS3) MAC address. The packet is sent to the

   corresponding = MAC-VRF and after a lookup of MAC DA, is forwarded = to

   the destination = TS (TS3) over the corresponding interface.  =

[Vincent]: Missing = the description of MPLS encapsulated case?

 

5.2 IRB forwarding on NVEs = with core-facing IRB Interface

=A1=AD

5.2.1 Control Plane Operation = for IRB forwarding with core-facing I/F

 

   Each NVE = advertises an RT-2 (MAC/IP Advertisement Route) for each = of

   its TSes and it = also advertises a single RT-2 for core-facing = IRB

   interface (which = is per tenant or per IP-VPN).

 

   The fields of = RT-2 for each TS are set as follow:

 

   - RD and ESI per = [EVPN]

   - Ethernet Tag = =3D 0; assuming VLAN-based service

   - MAC Address = Length =3D 48

   - MAC Address = =3D Mi ; MAC address of TS

   - IP Address = Length =3D 32 or 128

   - IP Address =3D = IPi ; IP address of TS

   - Label-1 =3D = MPLS Label or VNID corresponding to access-facing = EVI

[Vincent]: I have = read section 5.2.2, according to my understanding, the label carrying in = Label-1 field is not been used by =A1=B0Data Plane Operation for IRB = forwarding with core-facing I/F=A1=B1?

=A1=AD

5.2.2 Data Plane = Operation for IRB forwarding with core-facing = I/F

=A1=AD

   - On the egress = NVE, if the packet is VxLAN encapsulated, the = VxLAN

   header is = removed and the resultant Ethernet frame is fed into = the

   core-facing = MAC-VRF associated with that tenant based on the VNID. =

 

   - The MAC DA = lookup yields the core-facing IRB interface of = the

   egress NVE over = which the frame is sent. Next, the Ethernet header = is

   removed and a = lookup is performed based on IP DA in the = associated

   IP-VRF for that = tenant. The IP lookup yields the destination TS = (TS3)

   MAC address and = the access-facing IRB interface over which the = packet

   needs to be = sent.

 

   - The IP packet = is encapsulated with an Ethernet header with the = MAC

   SA set to that = of the access-facing IRB interface of the egress = NVE

   (NVE2) and the = MAC DA is set to that of destination TS (TS4) = MAC

   address. The = packet is sent to the corresponding MAC-VRF and after = a

   lookup of MAC = DA, is forwarded to the destination TS (TS3) over = the

   corresponding = interface. 

[Vincent]: Missing = the descrition of MPLS encapsulated case?

I have always thought that Historic RFCs describe something that has been i= mplemented and deployed, but new standards are now in force. E.g., original Martini drafts (which definitely have been implemented and d= eployed) have been published as Historic RFCs. For the sake of curiosity, is this the case with IPLS?

This deployment approach incurs a high risk of service interruption, since at least one domain will not offer PE node redundancy. This document describes an inter-domain VPLS solution that provides PE node redundancy across domains. This document is a product of the Layer 2 Virtual Private Networks Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet standards track protocol for the Internet community,and requests discussion and suggestions for improvements.

Please send substantive comments to the ietf@ietf.org mailing lists by 2014-08-07. This last call period has been lengthened to take into account IETF-90. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract A Virtual Private LAN Service (VPLS) is used to interconnect systems across a wide-area or metropolitan-area network, making it appear that they are on a private LAN. The systems which are interconnected may themselves be LAN switches. If, however, they are IP hosts or IP routers, certain simplifications to the operation of the VPLS are possible. We call this simplified type of VPLS an "IP-only LAN Service" (IPLS). In an IPLS, as in a VPLS, LAN interfaces are run in promiscuous mode, and frames are forwarded based on their destination MAC addresses. However, the maintenance of the MAC forwarding tables is done via signaling, rather than via the MAC address learning procedures specified in [IEEE 802.1D]. This draft specifies the protocol extensions and procedures for support of the IPLS service. The original intent was to provide an alternate solution to VPLS for those PE routers that were not capable of learning MAC address through data plane. This became non-issue with newer hardware. The concepts put forth by this draft are still valuable and are adopted in one form or other by newer work such as Ethernet VPN in L2VPN Working Group and possible data center applications. At this point, no further action is planned to update this document and is published simply as a historic record of the ideas. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-l2vpn-ipls/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-l2vpn-ipls/ballot/ No IPR declarations have been submitted directly on this I-D.

But I think you have made it as clear and concise as it could possibly have been. Good job! I have done my AD review and found no substantive issues. I do, however, have a little pile of nits. Actually, quite a large heap. Nothing to worry about, but if you could clean them up i think it would improve the document still further. The only topics that need real attention are those related to IANA. Let me know how you get on, and please object if my comments are wrong. Thanks, Adrian === It would be best to move the Introduction to be the first section in the document. --- Section 5 Ethernet segments have an identifier, called the "Ethernet Segment Identifier" (ESI) which is encoded as a ten octets integer. It would help if you said "...in line format with the most significant octet sent first." --- Section 5 In general, an Ethernet segment MUST have a non-reserved ESI that is unique network wide "In general" is not really consistent with "MUST" --- Do you want an IANA registry to track the values of the Type field of the ESI? --- There is some mixing of "octet" and "byte" in the document. This creates the impression that you mean something different by the two words. --- Could you expand DF on first use. You have it in 8.3. --- Section 6 You use "Ethernet Tag ID", "Ethernet Tag", and "Ethernet Tag Identifier" interchangeably. It would be helpful to use just one term and to check usage in the rest of the document. --- Section 6.1 In such scenarios, the Ethernet frames transported over MPLS/IP network SHOULD remain tagged with the originating VID and a VID translation MUST be supported in the data path and MUST be performed on the disposition PE. I think you should add under what circumstances the frames MAY be re- tagged with a different VID (or s/SHOULD/MUST). You don't need a detailed explanation, but a guide to the implementer/operator. --- Do you want IANA to create a registry and track the Route Types defined for the EVPN NLRI in Section 7? --- Section 7.1 and onwards... I know "RD" is a term of art in the context of BGP, but could you please expand RD it on first use rather than leaving that to 8.2.1. (All the forward references to later sections are good, thanks.) --- A small inconsistency between sections 7 and 8. In the figures in Section 7 you have "MPLS Label" and "MPLS Label1" etc. In the text in Section 8 you have "MPLS label" etc. When you refer to the fields you need to match the case. When you refer to the concept of an MPLS label, you can (of course) use normal case. --- Are you sure that the ESI Label extended community and subtypes don't need IANA intervention here? --- It would be nice if 7.5 included a hint as to what an "ESI label" is. --- In 7.10 If a PE uses RT-Constrain, the PE SHOULD advertise all such RTs using RT Constraints. Is this a general restatement of RFC 4684 (if so add "As described in [RFC4684]...") or new guidance for implementers of this spec (if so, what is the reason for SHOULD? is there a MAY to counter it?) --- 8.1.1 The Ethernet Segment Identifier MUST be set to the ten octet ESI identifier described in section 5. Would that be the ESII? :-) --- 8.2.1 has "MANDATORY" I guess you are inventing a 2119 term to counter- point "OPTIONAL". Please use "REQUIRED." --- In Section 13.1 In certain environments the source MAC address MAY be used to authenticate the CE and determine that traffic from the host can be allowed into the network. Want to hint which environments they would be. Possibly more important, want to say in which environments this would be a damn fool idea? --- 14.1.2 The MPLS label stack to send the packets to PE1 is the MPLS LSP stack to get to PE1 and the EVPN label advertised by PE1 for CE1's MAC. and The MPLS label stack to send packets to PE2 is the MPLS LSP stack to get to PE2 and the MPLS label in the Ethernet A-D route advertised by PE2 for , if PE2 has not advertised MAC1 in BGP. It *should* be perfectly obvious to the implementer, but perhaps you should say what order the labels appear on the stack since "and" is non- specific. --- Section 18 I wish you would add a reference to 4385 and use that control word with the various fields set to zero. This would keep us from increasing the number of different control word definitions in the wild. I think that the impact on your spec would be zero. --- Section 21 should be renamed "Contributors" --- I think RFC 2119 is a normative reference.

The IESG is in the process of updating its statement on "Designating RFCs as Historic". It includes the following text: An RFC may be published directly as Historic, with no earlier status to change (see, for example, RFC 4870). This is usually done to document ideas that were considered and discarded, or protocols that were already historic when it was decided to document them. Those publications are handled as are any other RFCs.

Here are a few comments. In some places the document says "VNI/VSID" to designate both the VXLAN and the NVGRE id, while in some other places simply "VNI" is used. I would suggest using "VNI" everywhere for brevity, and indicate in section 5.1 that "VNI" designates the VXLAN VNI or the NVGRE VSID, depending on which is used. The text in Section 5.1.2 remains partly obscure to me: * First of all, I believe that it should say upfront that it does not apply when locally significant VNIs are used. * I don't really get why Option 1 and Option 2 are presented, since it really seems like Option 1 with auto-derivation of RD and RT has all the advantages and no drawback. * the use of the notion of "subnet" should I think be avoided, given that this is an IP notion, and given that nothing prevents the use of multiple IP subnets on a same Ethernet broadcast domain (section 5.1.3 uses "bridge domain" which is possibly the choice to make here also) * (and assuming that Option 2 is worth documenting), the last sentence of the last paragraph describing Option 2 may need to be clarified: " In this option, the VNI/VSID in the data-plane is sufficient to identify a specific bridge domain - e.g., no need to do a lookup based on VNI/VSID field and Ethernet Tag ID fields to identify a bridge domain." -> Since " VNI/VSID field" and "Ethernet Tag ID" are names of fields in a MAC advertisement route, it is not obvious what it means to base a dataplane lookup on these fields -> The sentence may implicitly mean that in the other option (option 1) looking up the VNI in the dataplane would *not* be sufficient ; is this the intent ? if yes, why wouldn't such a lookup be sufficient to map a dataplane packet to the right EVI ? On Section 5.1.2.1 on auto-derivation of RT: First, I think the document should state explicitly that using auto-derived RTs is OPTIONAL. When auto-derivation is used, then the proposed text makes sense. My question is: if auto-derivation is *not* used, is the operator free of choosing any RT (including an RT with the bit corresponding to the "A" bit of an auto-derived RT set to zero), or should the operator avoid any value with the A bit set to one ? On section 5.1.3: * The three parts starting by "For the VNI based mode..." and "For the VNI-aware bundle mode...." (x2) seem to echo Option 1 "Single Subnet per EVI" and Option 2 "Multiple Subnets per EVI" of section 5.1.2. If this is the intent, then using consistent naming would be best. If not, then I believe there would need to be text describing what these modes are. * The section should state clearly that in the case where locally significant VNIs are used, then the Ethernet Tag field should be set to zero. * I believe that the text on the new values for the BGP Encapsulation extended community should have a value for MPLS-over-UDP * I believe that the text on the new values for the BGP Encapsulation extended community should be moved to the "IANA Considerations section" * What is the intent behind there "MPLS encapsulation value", given that an absence of BGP Encap ext comm has the same semantic ? Reading, in section 6, that "if the BGP Encapsulation extended community is not present, then the default MPLS encapsulation ___or a statically configured encapsulation___ is assumed" (emphasis mine), increases the confusion. On section 6: * "However, if this attribute is present, then an ingress PE can send a frame to an egress PE only if the set of encapsulations advertised by the egress PE..." => to clearly formulate how multiple encaps can be advertized, I would propose the following rewording: "If this BGP Encapsulation extended community is present at least once, an ingress PE can send a frame to an egress PE using one of the encapsulations specified in this/these extended communit(y/ties). This requires that the set of encapsulations advertised by the egress PE..."

Hi Ali,

I think the inter-as option-B solution in our draft is different from cu= rrent EVPN inter-as solution. The procedures are described as follows:

 

Assuming ASBR in NVO3 network is called ASBR-d, ASBR in EVPN network is = called ASBR-w.

 

Control plane process:

1. From DC to WAN side:

MPLS VPN Label is allocated on ASBR-d per ESI per VN, the usage of the V= N has no change from traditional NVO3 network,the VN has global significanc= e; For single-homed scenario, it is allocated per NVE per VN. Incoming forw= arding table is generated on ASBR-d. ASBR-d advertises the MAC/IP advertisement route with new allocated MPLS V= PN Label to peer ASBR-w.

 

2.From WAN to DC side:

VN ID is allocated per MPLS VPN Label, the VN ID has local significance = on ASBR-d.  Outgoing forwarding table is generated on ASBR-d. ASBR-d a= dvertises the MAC/IP advertisement route with new VN ID to local NVE.

 

Data plane process:

1.From DC to WAN side:

When a NVE receives traffic from local TS, the NVE performs MAC lookup i= n local VN, then it sends the traffic to ASBR-d using NVO3 encapsulation, V= N ID is the new allocated VN ID on ASBR-d, It can only have local significa= nce on ASBR-d. ASBR-d performs NVO3 decapsulation, switch VN ID to MPLS VPN Label, then performs MPLS encapsul= ation and sends to peer ASBR-w.

 

2. From WAN to DC side:

When ASBR-d receives traffic from peer ASBR-w, ASBR-d switches MPLS VPN = Label to local NVE+ VN ID and sends it to local NVE using NVO3 enc= apsulation. The VN ID in the NVO3 header has global significance on al= l NVEs.

 

In option-B solution, only VN ID and MPLS VPN Label switching is support= ed on ASBR-d, ASBR-d doesn't need to perform MAC look up, ASBR-d has more s= calability.

Subject: About inter-as option-B solution between NVO3 network and E= VPN network

 

Hi Ali,

I think the inter-as option-B solution in our dr= aft is different from current EVPN inter-as solution. The procedures are de= scribed as follows:

 

Assuming ASBR in NVO3 network is called ASBR-d, = ASBR in EVPN network is called ASBR-w.

 

Control plane process:

1. From DC to WAN side:

MPLS VPN Label is allocated on ASBR-d per ESI pe= r VN, the usage of the VN has no change from traditional NVO3 network,the V= N has global significance; For single-homed scenario, it is allocated per NVE per VN. Incoming forwarding table is generated on = ASBR-d. ASBR-d advertises the MAC/IP advertisement route with new allocated= MPLS VPN Label to peer ASBR-w.

 

2.From WAN to DC side:

VN ID is allocated per MPLS VPN Label, the VN ID= has local significance on ASBR-d.  Outgoing forwarding table is gener= ated on ASBR-d. ASBR-d advertises the MAC/IP advertisement route with new VN ID to local NVE.

 

Data plane process:

1.From DC to WAN side:

When a NVE receives traffic from local TS, the N= VE performs MAC lookup in local VN, then it sends the traffic to ASBR-d usi= ng NVO3 encapsulation, VN ID is the new allocated VN ID on ASBR-d, It can only have local significance on ASBR-d. ASBR-d performs = NVO3 decapsulation, switch VN ID to MPLS VPN Label, then performs MPLS enca= psulation and sends to peer ASBR-w.

 

2. From WAN to DC side:

When ASBR-d receives traffic from peer ASBR-w, A= SBR-d switches MPLS VPN Label to local NVE+ VN ID and sends it to = local NVE using NVO3 encapsulation. The VN ID in the NVO3 header has global significance on all NVEs.

 

In option-B solution, only VN ID and MPLS VPN La= bel switching is supported on ASBR-d, ASBR-d doesn't need to perform MAC lo= ok up, ASBR-d has more scalability.

Thanks

Yes, it is for scalability. NVO3 network and EVPN network can be inter-c= onnected through option-A or option-B method. Option-A is back-to-back conn= ection method, sub-interfaces associated with each MAC-VRF are created to c= onnect two ASBRs. If there are huge number of tenants and end systems in data center,  it will impose&nbs= p;big burden on ASBRs.

In option-B solution, only VN ID and MPLS VPN Label switching is needed = on ASBR, no need to create huge number of sub-interfaces and MAC-VRFs.

EVPN base protocol provides homogenous network inter-as option-B connect= ion method, for heterogeneous network, new technical points should be intro= duced, this draft describes inter-as option-B for heterogeneous network int= erconnection.

Subject: About inter-as option-B solution between NVO3 network and E= VPN network

 

Hi Ali= ,

I think the inter-as option-B solution in our draft is different = from current EVPN inter-as solution. The procedures are described as follow= s:

 

Assuming ASBR in NVO3 network is called ASBR-d, ASBR in EVPN netw= ork is called ASBR-w.

 

Control plane process:

1. From DC to WAN side:

MPLS VPN Label is allocated on ASBR-d per ESI per VN, the usage o= f the VN has no change from traditional NVO3 network,the VN has global sign= ificance; For single-homed scenario, it is allocated per NVE per VN. Incoming forwarding table is generated on = ASBR-d. ASBR-d advertises the MAC/IP advertisement route with new allocated= MPLS VPN Label to peer ASBR-w.

 

2.From WAN to DC side:

VN ID is allocated per MPLS VPN Label, the VN ID has local signif= icance on ASBR-d.  Outgoing forwarding table is generated on ASBR-d. A= SBR-d advertises the MAC/IP advertisement route with new VN ID to local NVE.

 

Data plane process:

1.From DC to WAN side:

When a NVE receives traffic from local TS, the NVE performs MAC l= ookup in local VN, then it sends the traffic to ASBR-d using NVO3 encapsula= tion, VN ID is the new allocated VN ID on ASBR-d, It can only have local significance on ASBR-d. ASBR-d perfor= ms NVO3 decapsulation, switch VN ID to MPLS VPN Label, then performs MPLS e= ncapsulation and sends to peer ASBR-w.

 

2. From WAN to DC side:

When ASBR-d receives traffic from peer ASBR-w, ASBR-d switches MP= LS VPN Label to local NVE+ VN ID and sends it to local NVE using N= VO3 encapsulation. The VN ID in the NVO3 header has global significance on all NVEs.

 

In option-B solution, only VN ID and MPLS VPN Label switching is = supported on ASBR-d, ASBR-d doesn't need to perform MAC look up, ASBR-d has= more scalability.

Thanks

Yes, it is for scalability. NVO3 network and EVP= N network can be inter-connected through option-A or option-B method. Optio= n-A is back-to-back connection method, sub-interfaces associated with each MAC-VRF are created to connect two ASBRs. If there ar= e huge number of tenants and end systems in data center,  it will impo= se big burden on ASBRs.

In option-B solution, only VN ID and MPLS VPN La= bel switching is needed on ASBR, no need to create huge number of sub-inter= faces and MAC-VRFs.

EVPN base protocol provides homogenous network i= nter-as option-B connection method, for heterogeneous network, new technica= l points should be introduced, this draft describes inter-as option-B for heterogeneous network interconnection.

Subject: About inter-as option-B solution between NVO3 network and E= VPN network

 =

Hi Ali,

I think the inter-as option-B solution in our dr= aft is different from current EVPN inter-as solution. The procedures are de= scribed as follows:

 

Assuming ASBR in NVO3 network is called ASBR-d, = ASBR in EVPN network is called ASBR-w.

 

Control plane process:

1. From DC to WAN side:

MPLS VPN Label is allocated on ASBR-d per ESI pe= r VN, the usage of the VN has no change from traditional NVO3 network,the V= N has global significance; For single-homed scenario, it is allocated per NVE per VN. Incoming forwarding table is generated on = ASBR-d. ASBR-d advertises the MAC/IP advertisement route with new allocated= MPLS VPN Label to peer ASBR-w.

 

2.From WAN to DC side:

VN ID is allocated per MPLS VPN Label, the VN ID= has local significance on ASBR-d.  Outgoing forwarding table is gener= ated on ASBR-d. ASBR-d advertises the MAC/IP advertisement route with new VN ID to local NVE.

 

Data plane process:=

1.From DC to WAN side:

When a NVE receives traffic from local TS, the N= VE performs MAC lookup in local VN, then it sends the traffic to ASBR-d usi= ng NVO3 encapsulation, VN ID is the new allocated VN ID on ASBR-d, It can only have local significance on ASBR-d. ASBR-d performs = NVO3 decapsulation, switch VN ID to MPLS VPN Label, then performs MPLS enca= psulation and sends to peer ASBR-w.

 

2. From WAN to DC side:=

When ASBR-d receives traffic from peer ASBR-w, A= SBR-d switches MPLS VPN Label to local NVE+ VN ID and sends it to = local NVE using NVO3 encapsulation. The VN ID in the NVO3 header has global significance on all NVEs. <= /p>

 

In option-B solution, only VN ID and MPLS VPN La= bel switching is supported on ASBR-d, ASBR-d doesn't need to perform MAC lo= ok up, ASBR-d has more scalability.

Subject: About inter-as option-B so= lution between NVO3 network and EVPN network

Hi Ali,

I think the inter-as option-B solution in our draft is different from cu= rrent EVPN inter-as solution. The procedures are described as follows:

 

Assuming ASBR in NVO3 network is called ASBR-d, ASBR in EVPN network is = called ASBR-w.

 

Control plane process:

1. From DC to WAN side:

MPLS VPN Label is allocated on ASBR-d per ESI per VN, the usage of the V= N has no change from traditional NVO3 network,the VN has global significanc= e; For single-homed scenario, it is allocated per NVE per VN. Incoming forw= arding table is generated on ASBR-d. ASBR-d advertises the MAC/IP advertisement route with new allocated MPLS V= PN Label to peer ASBR-w.

 

2.From WAN to DC side:

VN ID is allocated per MPLS VPN Label, the VN ID has local significance = on ASBR-d.  Outgoing forwarding table is generated on ASBR-d. ASBR-d a= dvertises the MAC/IP advertisement route with new VN ID to local NVE.

 

Data plane process:

1.From DC to WAN side:

When a NVE receives traffic from local TS, the NVE performs MAC lookup i= n local VN, then it sends the traffic to ASBR-d using NVO3 encapsulation, V= N ID is the new allocated VN ID on ASBR-d, It can only have local significa= nce on ASBR-d. ASBR-d performs NVO3 decapsulation, switch VN ID to MPLS VPN Label, then performs MPLS encapsul= ation and sends to peer ASBR-w.

 

2. From WAN to DC side:

When ASBR-d receives traffic from peer ASBR-w, ASBR-d switches MPLS VPN = Label to local NVE+ VN ID and sends it to local NVE using NVO3 enc= apsulation. The VN ID in the NVO3 header has global significance on al= l NVEs.

 

In option-B solution, only VN ID and MPLS VPN Label switching is support= ed on ASBR-d, ASBR-d doesn't need to perform MAC look up, ASBR-d has more s= calability.

Thanks

weiguo

Hence I would expect that Management Information Base for VPLS would provide for some representation of ACs that perform this function for a given VSI. However, this RFC does not even mention attachment circuits in any way. I have tried to raise this issue with the WG and the authors. One of the authors has replied (see http://www.ietf.org/mail-archive/web/l2vpn/current/msg04539.html) that "ACs are attached to the VPLS instances and are represented as IfMIB entries". However, neither Interfaces MIB nor any of its key elements (e.g., ifIndex) are mentioned in this RFC. Instructions: ------------- This erratum is currently posted as "Reported". If necessary, please use "Reply All" to discuss whether it should be verified or rejected. When a decision is reached, the verifying party (IESG) can log in to change the status and edit the report, if necessary. -------------------------------------- RFC7257 (draft-ietf-l2vpn-vpls-mib-15) -------------------------------------- Title : Virtual Private LAN Service (VPLS) Management Information Base Publication Date : July 2014 Author(s) : T.

Malis [agmalis@= gmail.com] Sent: Wednesday, July 23, 2014 9:14 AM To: l2vpn@ietf.org Subject: Some comments on draft-boutros-l2vpn-evpn-vpws-04 This morning I had a chat with Sami about the draft, to follow up on my com= ments in the l2vpn meeting. One thing we discussed is the commonality betwe= en this draft and RFC 6624. That commonality makes it easier for me to supp= ort this draft, but I would suggest that a reference to that RFC be added t= o the draft. In addition, that RFC is Informational, and this draft should = be as well, since it's just discussing a particular application for the Sta= ndards Track EVPN draft. Talking about RFC 6624, that RFC has the following statement: "...it is recommended that devices implementing the solution described in t= his document also implement the approach in [RFC4447] and [RFC6074]." This draft should also have a similar statement.

Hi authors,

To follow up on my comments in the l2vpn meeting, following two drafts p= roposed in L2VPN WG and L3VPN WG are for your reference:

-- draft-li-l3vpn-mvpn-role-state-ad-02
-- draft-zhang-l2vpn-evpn-selective-mcast-01
The role information is truly a possible way to help optimize the BUM traff= ic in EVPN. Regarding the possible solutions, I have following more comment= s:

-- It is better to work out a generic role-info advertisement solutions = based on all possible application scenarios.

-- Taking into account compatibility, it is better to define a new route= type for NLRI or a new attribute to advertis the role information. The ext= ension of PMSI Tunnel attribute may proposes compatibility issue for B= GP-based MVPN defined in RFC 6514.

 

 

Regards,

Zhenbin(Robin)

This can be equivalent to the vc-type VLAN in PWs. It should be 24-bit. We don't want to unnecessarily create EVIs because we 4K scale limit. It should be noted that you may have a single EVI for the whole network.=20 > >b) single-active MH behavior: >.- all-active MH behavior should be equivalent to EVPN (except for >split-horizon which does not make sense in VPWS) hence there is no need to >document. Since the concept of all-active multi-homing is new in P2P services, I think a short description is in order but it should be mentioned that it is per baseline-EVPN procedure. Besides, the text is brief. >.- in single-active MH the behavior is =B3slightly" different and MUST be >documented:=20 >In EVPN, for single-active MH, the two MH PEs (PE1 and PE2 for ESI1) will >send both their per ESI AD routes and per EVI AD routes.

Only the per-ESI AD route. Or we can follow the same procedure as baseline EVPN and send a MAC route with Ether-tag set to the service-id (as before) and with MAC set to NULL.

Hi Rabadan,

Thanks for your detailed clarification about the difference between draf= t-rabadan-l2vpn-evpn-optimized-ir-00 and draft-zhang-l2vpn-evpn-select= ive-mcast-01. It seems reasonable that they are used for difference applica= tion scenarios. But I am sorry that I proposed the inappropriate draft in the comment:) The L2VPN draft should b= e draft-li-l2vpn-evpn-mcast-state-ad-01. This draft is to advertise the sta= te information for the leaf node of the EVPN along with the Inclusive Multi= cast Ethernet Tag route. The possible application scenarios is to save bandwidth for ingress replication and fac= ilitate the egress PE protecion for P2MP MPLS. For draft-li-l3vpn-mvpn-role= -state-ad-02, we proposed the role information to be advertised in the= Intra-AS I-PMSI A-D route. At the beginning, we think the role information for EVPN maybe not necessary comparing with = BGP-based L3VPN since the unknown unicast always exists in the EVPN and eve= ry PE should be the root node. So it is only necessary to define the state = information for the leaf node. In the optimized-ir draft, you proposed the role information to be advertised= in the solution of central multicast replication. If the solution can be a= ccepted, we hope that the generic solution can be worked out to advertise t= he possible role information or state information to cope with all possible optimization scenarios for inc= lusive multicast trees in EVPN. Then it decouples the role/state informatio= n with tunnel information. If so, the tunnel type defined in the RFC6514 ca= n be reused and the new defined  role/state information community can be used for both EVPN and BGP-b= ased MVPN. It is not necessary to define the new tunnel type (AR) which may= be only used for the IR optimization solutions proposed by you.

 

 

 

Best Regards,

Robin

=D6=F7=CC=E2: Re: Comments on draft-rabadan-l2vpn-evpn-optimized-ir-= 00

Robin,

The scope of the current version of the optimized-ir draft is EVPN and= ingress replication for layer-2 BUM traffic. So I won=A1=AFt comment on th= e l3vpn draft for the moment. 
As for draft-zhang-l2vpn-evpn-selective-mcast-01, I understand it trie= s to add selective multicast trees to EVPN, which I agree is something that= was missing compared to RFC7117 for VPLS.

Selective multicast trees optimize the transport of specific IP multic= ast streams, setting up a different tree (type p2mp, IR, etc) to only those= nodes interested in those IP multicast streams.   
The optimized-ir draft addresses different issues. It actually modifie= s the IR tunnel type for inclusive multicast trees (BUM traffic). Because i= n reality we are just creating a different version of an IR tunnel:
  • We still use the inclusive multicast route (because it will still tell = the ingress PE where to send the BUM traffic)
  • We add a new tunnel type (because it is no longer IR) and new flag= s in the reserved bits of the PMSI tunnel attribute.
This new tunnel type (AR) and the AR-type field can actually be used i= n draft-zhang-l2vpn-evpn-selective-mcast-01 for selective multicast tr= ees if we needed to do the same optimization for selective multicast trees = that use IR.

I hope that explains better why we are not using a separate route-type= for this.
As for the compatibility, the solution is completely backwards compati= ble with the existing EVPN implementation, and it does not clash with MVPN = or VPLS-MCAST as described in the draft:
  • we are defining a new tunnel type, which should be discarded by PEs not= supporting the draft 
  • we are defining some flags, which are not clashing with the =A1=B0= L=A1=B1 flag defined in RFC6514, that you also use in the selective mcast t= ree draft
I hope this helps clarifying the draft.
Thank you.
Jorge

Subject: Comments on draft-rabadan= -l2vpn-evpn-optimized-ir-00

Hi authors,

To follow up on my comments in the l2vpn meeting, following two drafts p= roposed in L2VPN WG and L3VPN WG are for your reference:

-- draft-li-l3vpn-mvpn-role-state-ad-02
-- draft-zhang-l2vpn-evpn-selective-mcast-01
The role information is truly a possible way to help optimize the BUM traff= ic in EVPN. Regarding the possible solutions, I have following more comment= s:

-- It is better to work out a generic role-info advertisement solutions = based on all possible application scenarios.

-- Taking into account compatibility, it is better to define a new route= type for NLRI or a new attribute to advertis the role information. The ext= ension of PMSI Tunnel attribute may proposes compatibility issue for B= GP-based MVPN defined in RFC 6514.

Hi Jorge,

I have two comments:

1. More than one REPLICATOR scenario:

In a service where there is more than one or more REPLICATORs,
In per-flow loadbalancing mode:

Relies on LEAF=A1=AFs local traffic HASH algorithm, a packet can be sent to any one of the REPLICATOR = and replicated to destinations.Multicast traffic can be fully dispersed amo= ng all REPLICATORs.

In per-VNI mode:

To ensure traffic loadbalancin= g among multiple REPLICATORs,each REPLICATOR should announce VNI List or mul= ticast group range to all leafs, the VN List or multicast group on each REP= LICATOR is configured by operators in beforehand. For example if there are = two REPLICATORs and 100 VN in NVO3 network, REPLICATOR1 can be responsible for VNI 1-50 multicast traffic for= warding, REPLICATOR2 is responsible for VNI 51-100. When a leaf receives mu= lticast traffic from local connecting TS, if the TS belongs to VNI 1-50, th= e traffic will be sent to REPLICATOR1;If the TS belongs to VNI 51-100, the traffic will be sent to REPLICATOR2.

EVPN protocol should be extended to support VNI List or multicast group range advertisement.

 

 

2. Hierarchical REPLICATOR-LEA= F:

Hierarchical REPLICATOR-LEAF should be supported, i.e, a device can be REPLICATOR and LEAF at the same = time, for lower LAYER network, its REPLICATOR;For upper layer network, its = LEAF.

Thanks

weiguo

Yes it is, generic YANG model steup the base framework. It c= an be extended to add tools as well as other elements as well technology de= viations. Alarms etc either be part of this document will be a separate doc= ument that specifies them. That is the reason we have designed the model as= modular as possible and extensible as possible.

Please let us know if any of the parts are not ext= ensible or not modular enough.

Exactly, d= ifferent layer may have different addressing schemes. But I am wondering wh= ich layer the flow entropies are applied? L2, L3, MPLS layer?

I am aware of that, but this is different, MEF YANG model is specifically f= or Ethernet and structure does not allow to bring different addressing sche= mes other than MAC address. Additionally the proposed standard allow to add= flow entropies and facilitate nested OAM between different technologies. You may have to read in to the details= to see the actual differences.

Hi Tissa,
I feel that clear defini= tion of the scope of work is important. From reading the documents, my impr= ession, is that on-demand OAM tools that support detection and localization= of Loss of Continuity defect are in scope while the rest of OAM is for fur= ther study. I think that it would benefit the documents and discussion if s= cope be firmly set.

Regards,
Greg

= Yes it is, generic YANG model steup the base framework. It can be extended = to add tools as well as other elements as well technology deviations. Alarm= s etc either be part of this document will be a separate document that spec= ifies them. That is the reason we have designed the model as modular as pos= sible and extensible as possible.

Please let us know if any of the parts are not extensible or not modular en= ough.

Thanks
Tissa

Hi= Tissa, authors, et. al,
I've read documents an= d would like to clarify scope of these documents. OAM is not limited to pin= g and traceroute functions. It even not limited to continuity check. And in= connectionless networks there would not be connectivity verification. And the performance= measurement is the big part of OAM as well as protection coordination, def= ect alarms, and etc. Hence my question, is it in plans of the authors to ad= dress all of OAM in respective documents?

Regards,
Greg
