Hi all,

Section 3.2.2.1 of RFC 6074 requires encoding of VPN IDs for auto-discovery purposes as Ex= tended BGP Community attribute of BGP.

It further specifies that the following subtypes of = extended community can be used for this purpose:

·         2-octet AS specific= extended community. To the best of my understanding, if this subtype is us= ed for encoding a L2VPN ID, the provide should use the 2-octet AS number as= signed to it as part

·         IP address-specific= extended community.

 

It seems that RFC 6074 does not provide any way to u= se 4-octet AS numbers for encoding L2VPN IDs. Is this correct?

If yes, are there any plans to augment RFC 6074 in s= uch a way as to facilitate usage of 4-octet AS numbers in l2VPN ID encoding= ?

 

Regards, and lots of thanks in advance

Jim,

It is ok to use bgp as database distribution protocol and to= carry more then pure routing/reachability state. We are indeed past that p= oint. But only to the extend where distributed information is usefull at mu= ltiple end points.

However I do not see p2mp nature of BGP distribution to gene= rally fit policy or configuration needs.

Those are very often targeted to specific end point and I do= not think that sending them to all or for that matter filtering from all-1= with say RTC is really a wise approach.

Rgs,
R.

[weiguo2]: I know what you said. Yes, In IRB scenario, not only ethernet he= ader but also IP header can be used for traffic filtering.=C2=A0 I think ou= r draft can cover this scenario. In the draft, component types include both= IP and ethernet part, IP component types are inherited from RFC[5575], MAC= componet types are newly defined. So only one address family is needed for= IP and Ethernet traffic filtering.

[SLI] Right, that's one possibility, the other one could be to not crea= te a new AF for MAC FS but just extend the current FS address-families (VPN= and non VPN) with MAC component types and new actions.
The main question in term of protocol design is to we want to keep filterin= g AF agnostic (single FS AF for all type of flows) or do we need to keep se= parate FS AFs ?
[Jim U>] This comes back to a more basic question. Should an AF be defin= ed that communicates non-routing state? As an ex, VPLS BGP, FS, RTC the lis= t goes on are all delineated by AF.. At some point we need to acknowledge t= hat we are using BGP as a general distribution protocol and have the design= /spec reflect that. IMO this means separating by configuration type of acti= ons that do not require a global invariant and routing which does.
The way taken for the moment is to have separate ones, we can see that IPv6= FS is currently defined as a new couple of AFI/SAFI but is it the good way= to do ? I don't remember if this has been discussed or not when defini= ng FS IPv6 ?
I'm wondering if we cannot make FlowSpec working as IPFIX for the flow = definition.

[weiguo]: Thanks. But MAC filters maybe not applicable to IPV4 &VPNv4, = because in this case, MAC information will be changed on different PE devic= es, a single ACL rule can't identify a consistant flow at different PE = devices. So in IP network, flow-spec can only be defined using IP related i= nformation.
[SLI] I agree with your point but I was thinking about a future (hope it wi= ll happen :) when we will be able to offer L2 and L3 services on the same p= lug (including same VLAN, sort of concurrent routing & bridging interfa= ce). In this situation, is it good to use two address families to filter th= e different services ? Why not using only one ...

[weiguo2]: I know what you said. Yes, In IRB scenario, not only ethernet he= ader but also IP header can be used for traffic filtering.=C2=A0 I think ou= r draft can cover this scenario. In the draft, component types include both= IP and ethernet part, IP component types are inherited from RFC[5575], MAC= componet types are newly defined. So only one address family is needed for= IP and Ethernet traffic filtering.

[weiguo]: RD usage has no difference with original BGP VPN definication. Ca= n you give me some more clarifications?
[SLI] Right, but RFC5575 precises that RD is part of NLRI for VPN :
"The NLRI format for this address family consists of a fixed-length =C2=A0 =C2=A0Route Distinguisher field (8 bytes) followed by a flow specifi= cation,
=C2=A0 =C2=A0following the encoding defined in this document.=C2=A0 The NLR= I length
=C2=A0 =C2=A0field shall include both the 8 bytes of the Route Distinguishe= r as
=C2=A0 =C2=A0well as the subsequent flow specification.
"
In your document , I can't see this ... as you are defining a new NLRI,= you need to precise the format.

[weiguo2]: OK. In our draft, the format is same with RFC5575, I can add the= same description to make it more clear.

Hi,

I think this is a valuable addition, but I would like to see these MAC filt= ers being applicable also to IPv4 plugs (FS IPv4 & VPNv4)
[weiguo]: Thanks. But MAC filters maybe not applicable to IPV4 &VPNv4, = because in this case, MAC information will be changed on different PE devic= es, a single ACL rule can't identify a consistant flow at different PE = devices. So in IP network, flow-spec can only be defined using IP related i= nformation.

Moreover , the new AFI/SAFI should not be restricted to EVPN, any L2 interf= ace may be interested by such filter (VPLS, basic L2 switching ...).
[weiguo]: Yes, I agree. Firstly i propose Ethernet flow-spec only in EVPN n= etwork, because flows-pec relies on BGP protocol and EVPN has BGP control p= lane, so it will be easy to deploy BGP flowspec in EVPN network. If we want= to deploy the flow-spec in VPLS network, normally VPLS only relies on LDP = protocol, additional protocol of BGP flow-spec should be deployed for MAC f= iltering.
If the community thinks it is necessary to introduce ethernet flow-spec for= all L2 interface, i can update this part to let it not be restricted to EV= PN.

Route distinguisher may be is missing ...
[weiguo]: RD usage has no difference with original BGP VPN definication. Ca= n you give me some more clarifications?

Now more globally, may be it's time to think more globally about the ev= olution of FS. I pretty see FS evolution largely beyond DDoS domain. FS is = a very good protocol for SDN applications. The question behind is do we rea= lly need to work with multiple address families for each type of "serv= ice"/"interface type" to filter or do we need to have a more= global model where we would be able to put any type of filter any where an= d apply multiple actions (openflow like FS). Compared to openflow, FS has t= he magic to enable multipoint distribution of actions.

[weiguo]: Yes, BGP flow-spec can be applicable for some SDN applications. I= t has more potential to do more attactive things.

Best Regards,

Stephane

Weiguo,

=C2=A0 =C2=A0 =C2=A0 =C2=A0 I would like to better understand how a remote = PE will "learn" that it needs to deliver a FS path to the ingress= PE?? It cannot come from the CE as that is data plane learning. I would th= ink that all FS paths have to be disseminated by a centralized controller.<= br>

granted and the patent application numbers have been replaced with the patent numbers. The terms of this disclosure is IDENTICAL to the previous disclosure. However, there seems to be one additional patent application added to the list. The previous list included five patents and the new list has six. It seems like this sixth one was not disclosed by mistake as Cisco IP department was notified of this application related to this IETF draft by Cisco co-authors over a year ago. I believe at the end of the day, I am responsible for it and I should have double checked but it was an honest mistake and as noted there the terms of this disclosure remains identical to the previous one.

Hi all,

Section 3.2.2.1 of RFC 6074 requires encoding of VPN IDs for auto-discovery purposes as Ex= tended BGP Community attribute of BGP.

It further specifies that the following subtypes of = extended community can be used for this purpose:

·         2-octet AS specific= extended community. To the best of my understanding, if this subtype is us= ed for encoding a L2VPN ID, the provide should use the 2-octet AS number as= signed to it as part

·         IP address-specific= extended community.

 

It seems that RFC 6074 does not provide any way to u= se 4-octet AS numbers for encoding L2VPN IDs. Is this correct?

If yes, are there any plans to augment RFC 6074 in s= uch a way as to facilitate usage of 4-octet AS numbers in l2VPN ID encoding= ?

Dear Authors, et.al,

please kindly consider my comments and questions to = this document:

·         Introduction

o    “… it is a reasonable choi= ce to develop the unified OAM framework based on those (CFM) concepts.̶= 1; I agree that for packet switching connection-oriented networks that are = based on G.800 architecture CFM, but more so Y.1731, provides shared concepts. I think that the same cannot be said for connectionless p= acket switching networks. Thus extending CFM model onto arbitrary networks = without consideration whether these are connection-oriented or connectionle= ss is very questionable approach, IMO;

 

 

[Answer] As stated abo= ve it is the OAM Model that is leveraged here. Regardless of connection ori= ented or not the model on Fault domains, Test points etc is valid.

 

In theory connection o= riented can be broken in to connection establishment and data forwarding. W= ith that in mind, one can define Fault domain and test points. Followed by = definition of the Fault identifications tools accordingly.

 

Do you have a preferre= d OAM tool  for fault verification/isolation and loss and performance = monitoring for connection oriented connectuons ?. If so would like to revie= w and map to the model.

 

GIM>> I don̵= 7;t have “favorite tool” but would point that in connectionless= network one cannot define Mis-connection defect and thus OAM models for &n= bsp;connectionless and connection-oriented networks would be different.

 

o   “…CFM, it is a reasonable choice= to develop the unified OAM framework based on those concepts” IP OAM= is not based on Ethernet Service OAM model or principles but, IMO, OAM of = overlay networks more closer resemble IP OAM as these networks are connectionless in their architecture;

 

[Answer]  Please = see the answer above and extended CFM model. It is the model that is presen= ted here, regardless of the connectioness,  OAM tools need fault domai= ns and fault boundaries. Addidtionally as stated in the explanation above, there is nothing Ethernet in CFM, once the addre= ssing is decoupled.

 

o   “The YANG model presented in this docu= ment is the base model and supports IP Ping and Traceroute.” If only = these and similar OAM tools, e.g. LSP ping, Loopback/Linktrace, are in scop= e of the document, then, I believe, the title may say something like “YANG model of on-demand OAM tool to detect a= nd localize Loss of Continuity defect”. Referring to ping/traceroute = as “generic OAM” comes as stretch too far;

 

[Answer] I think there= is a miss understanding this model is not limited to Ping and Trace route.= Ping and traceroute are only examples to get the work stared and discussio= n going. As we go along other tools will be mapped to the model.

 

GIM>> LSP Ping d= oes more that ICMP or CFM’s Loopback and Linktrace as it verifies cor= relation between control and data planes. Had that functionality been remov= ed by TRILL OAM from “extended CFM model”?

 

o    “…initiate a performance m= onitoring session can do so in the same manner regardless of the underlying= protocol or technology” I’d point to work of LMAP WG on inform= ational model of performance measurements in large-scale access networks, work of ITU-T’s SG15, MEF. Perhaps sentence can be stopped= after “… or a Traceroute”.

[Answer] I did not ful= ly understand your point.

 

o   “In this document we define the YANG m= odel for Generic OAM” Can you provide definition or reference to the = definition of the “Generic OAM”? It is challenging to validate = informational model of something that not been sufficiently defined.

 

[Answer]  As expl= ained earlier terminology generic OAM is used to indicate that the presente= d OAM model can be applied independent of the underlying technology. In sec= tion 1, we have stated the following: “..In this document, we take the [8021Q] CFM model and extend it to a technology= independent framework and build the corresponding YANG model accordingly. = The YANG model presented in this document is the base model and supports IP= Ping and Traceroute. The generic OAM YANG model is designed such that it can be extended to cover various t= echnologies. Technology dependent nodes and RPC commands are defined in tec= hnology specific YANG models, which use and extend the base model defined h= ere. …. “

 

GIM>> Had other = WGs agreed that the proposed by TRILL WG OAM model is representative of the= ir technologies? If not, then what “Generic” is there?

 

·         Section 3

o   “This allows users to traverse between= OAM of different technologies at ease through a uniform API set.” Us= ually relationships between OAM layers referred and viewed as OAM interwork= ing. There are several examples of IETF addressing aspects of OAM interworking. I think that interworking includes not only s= cenarios of nested OAM layers but peering layers and thus is broader than i= ntroduced in the document “nested OAM”.

[Answer]  Can you= please provide some example here, I am not quite clear.<= /p>

 

Guessing from the word= peering, if we are referring to cascaded sections of different technologie= s such as IP Cloud, MPLS cloud and another IP cloud. Then the model present= ed here is the answer. You can have an end end OAM session at a higher MD-Level. Each of the clouds below can = have separate OAM at a lower MD-Level. These can be utilized for fault isol= ation.

 

o   Figure 1 depicts OAM of both connection-orie= nted and connectionless networks. What you see common, generic in respectiv= e OAM of these networks?

 

[Answer] Please see th= e answers above.

 

·         Section 4

o   “In IP, the MA can be per IP Subnet &#= 8230;” As there’s no definition of MA in IP, is this the defini= tion or one of examples. Can MA in IP network be other than per IP Subnet?<= o:p>

[Answer] It is “= .. can be”, so it meant to be an example and other possibilities are = not ruled out and model does not assume any such limitation.

 

o   “Under each MA, there can be two or mo= re MEPs (Maintenance End Points)” Firstly, since you adopt MA-centric= terminology, MEP stands for Maintenance Association End Point. Secondly, i= n some OAM models Down and Up MEP being distinguished. Would your model consider that? As there’s no definition of MEP for = several networks you’ve listed, e.g. IP, how the YANG model will abst= ract something that is not defined? And thirdly, how and where MIPs are loc= ated in IP OAM?

 

[Answer] Yes model acc= ept both UP/Down.

 

One cannot say for IP = there is no MEP. MEP is a functional abstraction of a test point that gener= ate and respond to OAM messages. In that regard IP devices today have an im= plicit MEP at the CPU. The model allow to provide more semantics to the MEP and allow to create UP/Down per inter= face or other scope, hence providing more granularity in fault isolation/ve= rification and monitoring.

 

GIM>> Is IP MEP = being defined as being in control plane/CPU? What if it is in NPU, i.e. dat= a plane? If on CPU, then what differentiates Up MEP from Down MEP from POV = of packets it transmits and receives? And how MIP functions in IP based on TRILL OAM model? Is it, as in Ethernet OA= M, constructed of two MHFs?

 

Thank you for your consideration of my notes and loo= king forward to the interesting discussion.

 

Thank you for spending= time to review and comment. We are updating the next version with comments= received so far and specifically during IETF in Canada. We are more than h= appy enhance where applicable or need more clarity.

RFC 7361 Title: LDP Extensions for Optimized MAC Address Withdrawal in a Hierarchical Virtual Private LAN Service (H-VPLS) Author: P. Dutta, F. Balus, O. Stokes, G. Calvignac, D. Fedyk Status: Standards Track Stream: IETF Date: September 2014 Mailbox: pranjal.dutta@alcatel-lucent.com, florin.balus@alcatel-lucent.com, ostokes@extremenetworks.com, geraldine.calvignac@orange.com, don.fedyk@hp.com Pages: 27 Characters: 62854 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-l2vpn-vpls-ldp-mac-opt-13.txt URL: https://www.rfc-editor.org/rfc/rfc7361.txt RFC 4762 describes a mechanism to remove or unlearn Media Access Control (MAC) addresses that have been dynamically learned in a Virtual Private LAN Service (VPLS) instance for faster convergence on topology changes. The procedure also removes MAC addresses in the VPLS that do not require relearning due to such topology changes. This document defines an enhancement to the MAC address withdraw procedure with an empty MAC list (RFC 4762); this enhancement enables a Provider Edge (PE) device to remove only the MAC addresses that need to be relearned. Additional extensions to RFC 4762 MAC withdraw procedures are specified to provide an optimized MAC flushing for the Provider Backbone Bridging (PBB) VPLS specified in RFC 7041. 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 your responses on the routing-discussion list. We have been working on a draft charter for the "BGP Enabled Services" working group (BESS) that will take over the BGP VPN work from L3VPN, L2VPN, and NVO3. You can see the working copy of this charter at https://datatracker.ietf.org/doc/charter-ietf-bess/ We will need to make specific decisions about which documents go where, but that will (hopefully) not change the discussion of the charter text. To move this forward, the IESG will consider this on 2nd October with a view to sending it out for formal IETF review. So your review comments now would be really helpful.

This draft is a work item of the Layer 2 Virtual Private Networks Working Group of the IETF. Title : Ethernet-Tree (E-Tree) Support in Virtual Private LAN Service (VPLS) Authors : Yuanlong Jiang Lucy Yong Manuel Paul Frederic Jounay Florin Balus Wim Henderickx Ali Sajassi Filename : draft-ietf-l2vpn-vpls-pe-etree-04.txt Pages : 23 Date : 2014-09-29 Abstract: A generic Virtual Private LAN Service (VPLS) solution is proposed for Ethernet-Tree (E-Tree) services which uses VLANs to indicate root or leaf traffic. A VPLS Provider Edge (PE) model is illustrated as an example for the solution. In the solution, E-Tree VPLS PEs are interconnected by PWs which carry the VLAN indicating the E-Tree attribute, the MAC address based Ethernet forwarding engine and the PW work in the same way as before.

=D6=F7=CC=E2: Questions about the draft of "A new Designated Fo= rwarder Election for the EVPN"

Hi Co-authors,
In all-active connection case, to avoid frame duplication and looping, only= one exit point multiple PEs corresponding to a ESI is allowed to egress BU= M traffic from EVPN network to local access network among . DF election alg= orithm is a candidated solution. To overcome some DF election drawbacks,this draft proposed a new algorithm= to replace DF election algorithm.

IEEE802.1AX,DRNI specs also ca= n meet EVPN active-active connection requirements. Do you have plan to use = IEEE existing standard to solve the problem?

Thanks

Giles,

Just FYI =96 there was a poll at the IETF90 for WG adoption of this dr= aft and there was a good consensus for it.  Here is the excerpt from&n= bsp;l2vpn@jabber.ietf.org:



[17:22:54] <adr= ianfarrel> Well, we're in Ali's presentation at the moment
[17:29:37] <adr= ianfarrel> how many have read -- "a good amount"
[17:31:39] <adr= ianfarrel> wg adoption? -- "mainly the same people as have
read"

Given that there was a good consensus for it, can we initiate the WG c= all for it?

Thanks,
Ali
