This draft is a work item of the Multiprotocol Label Switching WG of the IETF. Title : RSVP-TE Summary Fast Reroute Extensions for LSP Tunnels Authors : Mike Taillon Tarek Saad Rakesh Gandhi Abhishek Deshmukh Markus Jork Vishnu Pavan Beeram Filename : draft-ietf-mpls-summary-frr-rsvpte-03.txt Pages : 18 Date : 2019-05-02 Abstract: This document defines Resource Reservation Protocol (RSVP) Traffic- Engineering (TE) signaling extensions that reduce the amount of RSVP signaling required for Fast Reroute (FRR) procedures and subsequently improve the scalability of the RSVP-TE signaling when undergoing FRR convergence after a link or node failure. Such extensions allow the RSVP message exchange between the Point of Local Repair (PLR) and the Merge Point (MP) to be independent of the number of protected Label Switched Paths (LSPs) traversing between them when facility bypass FRR protection is used. The signaling extensions are fully backwards compatible with nodes that do not support them.

[See also my response to Mirja] I think this wibbliness may be due to a disagreement about whether it = was even necessary to specify how the FIB was constructed since the = process is just SR as usual. But (of course) we have the text and we = must get it right. Your suggestion is the right way forward. That is, text that is generic = and definitive (the main Section 3.1), and more detailed text that is = the examples currently present with the 2119 language removed (moved = into 3.1.1). > (2) Tunnel Endpoints > > =C2=A72: "The tunnel selected MUST have its remote end point = (destination) address > equal to the address of the next SR-MPLS capable node along the path = (i.e., the > egress of the active node segment)."

OK.=20 This is a little more complicated than it appears. When the tunnel ends, the revealed packet will be an MPLS-SR packet, so = it is clearly important that the tunnel can only end at an SR-MPLS = capable node. Now, the tunnel ingress must know the identity of the egress. That is, = to tunnel you have to tunnel to somewhere. There are two ways the tunnel ingress can do this: - by extracting that information from the SID stack - by learning from a routing protocol The latter could be done by building an overlay topology map from the = IGP information that identifies the SR-capable nodes. But this would = also need some smarts because otherwise you would end up with a full = mesh of tunnels. A better way of achieving it for the case in figure 1 = would be using a VPN-like solution such as that described in = draft-ietf-bess-datacenter-gateway. But what we have chosen to do is focus on the case where the tunnel = targets the next node in the SID stack. If you think about it, even in = the case for figure 1, the remote site might be dual homed and it will = be important to select the correct entry point, a feature that is only = made possible by directing the tunnel (possibly based on routing = information as suggested in draft-ietf-bess-datacenter-gateway) to the = correct entry point since otherwise the IP-enabled connecting network = will just use a shortest path approach. This means that there can be a variety of nodes on the packet's path as = explained in Section 3.2. There are six types of node and one of them = is: | o Transit nodes that are SR-MPLS capable but that are not identified | by a SID in the SID stack. Thus you are right that the text needs to be fixed. It really should be "The next SR-MPLS-capable node identified as being = on the SR path." That is, "The egress of the active node segment" in all = cases. > I realize that the sentence after the statement above is "This is = shown in > Figure 1." Figure 1 is a degenerate case of the (almost) general case = from > Figure 2. Even in the single tunnel (Figure 1) case, "the egress of = the active > node segment" doesn't have to be R2, it could be another node inside = the > SR-MPLS network (as R2, being SR-MPLS aware, should be able to forward = the > frames). No, I don't think it can. While I understand that you *could* tunnel to R2 for a segment that ends = beyond R2, I don't see how you would know to make/use that tunnel unless = there was some programming at R1 to tell it that. (See the discussion = above). And, in summary, this is not the solution we have documented. > 1. It is wrong. I think that what makes it wrong is the clarification = that > "the next SR-MPLS capable node along the path" is "the egress of the = active > node segment". Taken the text is parenthesis out would solve this = issue. As above, it will now read: The tunnel selected MUST have its remote end point (destination) address equal to the address of the next SR-MPLS capable node = identified as being on the SR path (i.e., the egress of the active node = segment). > 2.

This draft is a work item of the Multiprotocol Label Switching WG of the IETF. Title : Resilient MPLS Rings and Multicast Authors : Zhaohui Zhang Santosh Esale Filename : draft-zzhang-mpls-rmr-multicast-03.txt Pages : 7 Date : 2019-05-07 Abstract: With Resilient MPLS Rings (RMR), although all existing multicast procedures and solutions can work as is, there are optimizations that could be done for RSVP-TE P2MP tunnel signaling and Fast-ReRouting for both mLDP and RSVP-TE P2MP tunnels. This document describes RMR multicast on a high level, with detailed protocol procedure for RSVP- TE P2MP optimizations specified in a separate document. This document also discusses end to end multicast when there are RMRs.

The ingress LSR may also send PATH messages in both directions, so that the tunnel is set up in such a way that minimum delay is incurred for traffic to reach all leaves. Alternatively, the ingress may send PATH message only in one direction for best bandwidth utilization. For example, a leaf D is three hops away from the ingress A in clockwise direction (A,B,C,D) and four hops away in the other direction (A,E,F,G,D), but G is also a leaf so it may be better to just send the PATH message in the anticlockwise direction. Each router establishes forwarding state accordingly. Transit routers switches traffic towards downstream. A transit router could also be a leaf router and in that case it does "drop and continue" - sends traffic off the ring and switches traffic downstream. 2.1. Tunnel Protection and FRR Each node on a ring signals two counter-rotating MP2P RSVP-TE LSPs to itself. As these LSPs are self-signaled after the discovery of the ring, they can be used to protect P2MP LSPs on ring. So neither mLDP nor RSVP-TE has to setup a separate P2P bypass LSPs for link and node protection. [hvh] This is clear. I also did not find any indication how this optimisation has to be deployed. Do all the nodes in the ring, or in the network have to support this optimisation before it becomes effective. Zzh> The context is RMR - Resilient MPLS Ring.

[hvh] when you use the word "optimize" I expect an indication of the effect of the optimization on performance, or used resources. Zzh2> I see. The optimization is on (simpler) procedures and (less) resourc= es. I don't think we need to quantify it. [hvh-2] I would like to know why I should deploy this "optimisation", and maybe others would like to know too.

All,

 

I’ve been selected as an MPLS-RT reviewer for draft-z= zhang-mpls-rmr-multicast,
which is currently a candidate for MPLS WG adoption.

 

In the abstract is stated:

   With Resilient MP=
LS Rings (RMR), although all existing multicast
   procedures and so=
lutions can work as is, there are optimizations that
   could be done for=
 RSVP-TE P2MP tunnel signaling and Fast-ReRouting
   for both mLDP and=
 RSVP-TE P2MP tunnels.

I have = carefully read the draft but I could not find any justification
for the optimisation that could be done.

 =

Zzh> By “justif= ication", do you mean “need”? I thought the following text= provides that:

 =

 &nb= sp; For a conventionally signaled RSVP-TE P2MP tunnel, an ingress LS= R

 &nb= sp; discovers leaves and signals one sub-LSP for each leaf.  Even though

 &nb= sp; the forwarding state is merged at each hop (i.e, one incoming la= bel

 &nb= sp; mapping to multiple outgoing entries), the control plane maintai= ns

 &nb= sp; individual sub-LSP state.  This leads to lots of redundant state on

 &nb= sp; routers close to the ingress.

[hvh] &= quot;lots of state" - can you be more specific? is the redundancy 10% = or 90% ?

Zzh2> Depending on ho= w many leaves you have. With traditional RSVP-TE P2MP, there is one sub-LSP= to each leaf. If you have 20 leaves, the saving is 95% (I mean you only need to maintain 5% of state compared to tradition= al way). If you have 10 leaves, the saving is 90%. I don’t think the = draft needs to quantify it.

[hvh-2]= the draft should mention it because it may be a reason to apply the
optimization or not.

[hvh-2] if a leave is deleted, added, or changed all leaves will be notifie= d and will
have to process the notification.


Zzh> Or do you mean &= #8220;why” the optimization COULD be done? The key is that this is a = ring, and:

 =

 &nb= sp; … As the PATH message passes along the ring, the leaves

 &nb= sp; send RESV messages, but only one RESV message reaches the tunnel=

 &nb= sp; ingress.

[hvh] c= an you explain why only one RESV message reaches the tunnel ingress?

Zzh2> Because only on= e PATH message is sent, and the RESV state gets merged accordingly along th= e way.

[hvh-2]= the merging requires processing resources.


 Zzh> If you mea= n “how” it is done, I thought the following describes it:

 =

 &nb= sp; … With RMR, this can be optimized such

 &nb= sp; that only a single LSP is signaled, with all the leaves listed i= n the

 &nb= sp; PATH message.  As the PATH message passes along the ring, the leaves

 &nb= sp; send RESV messages, but only one RESV message reaches the tunnel=

 &nb= sp; ingress.

 

 &nb= sp; The ingress LSR may also send PATH messages in both directions, = so

 &nb= sp; that the tunnel is set up in such a way that minimum delay is

 &nb= sp; incurred for traffic to reach all leaves.  Alternatively, the ingress

 &nb= sp; may send PATH message only in one direction for best bandwidth

 &nb= sp; utilization.  For example, a leaf D is three hops away from the<= /p>

 &nb= sp; ingress A in clockwise direction (A,B,C,D) and four hops away in= the

 &nb= sp; other direction (A,E,F,G,D), but G is also a leaf so it may be b= etter

 &nb= sp; to just send the PATH message in the anticlockwise direction.

 

 &nb= sp; Each router establishes forwarding state accordingly.  Transit

 &nb= sp; routers switches traffic towards downstream.  A transit router could

 &nb= sp; also be a leaf router and in that case it does "drop and co= ntinue" -

 &nb= sp; sends traffic off the ring and switches traffic downstream.

 &nb= sp; itself.  As these LSPs are self-signaled after the discovery of the

 &nb= sp; ring, they can be used to protect P2MP LSPs on ring.  So neither mLDP

 &nb= sp; nor RSVP-TE has to setup a separate P2P bypass LSPs for link and= node

 &nb= sp; protection.

[hvh]&n= bsp; This is clear.


I also = did not find any indication how this optimisation has to be
deployed. Do all the nodes in the ring, or in the network have to
support this optimisation before it becomes effective.

 =

Zzh> The context is R= MR – Resilient MPLS Ring. All routers on the ring need to support RMR= and the multicast optimization for this to be effective. I can make that clear.

[hvh] O= K. Thanks.


 I= think these issues have to be documented before this draft can

be adop= ted as WG draft.

 =

Zzh> Besides explicitly stating that all rou= ters on the ring need to support the RSVP-TE P2MP optimization for it to be effective, please advise further how the first issue can be b= etter documented.

[hvh] w= hen you use the word "optimize" I expect an indication of
the effect of the optimization on performance, or used resources.

 =

Zzh2> I see. The opti= mization is on (simpler) procedures and (less) resources. I don’t thi= nk we need to quantify it.

[hvh-2] I would like to know why I should deploy this "optimisation&qu= ot;,
and maybe others would like to know too.

Zzh2> I will update t= he draft to point out that all routers on the ring needs to support the opt= imization – please let me know if that is enough.

Zzh2> Thanks!<= o:p>

Zzh2> Jeffrey<= o:p>

Best regards, Huub.

This draft is a work item of the Multiprotocol Label Switching WG of the IETF. Title : SR-MPLS over IP Authors : Xiaohu Xu Stewart Bryant Adrian Farrel Syed Hassan Wim Henderickx Zhenbin Li Filename : draft-ietf-mpls-sr-over-ip-05.txt Pages : 18 Date : 2019-05-10 Abstract: MPLS Segment Routing (SR-MPLS) is an MPLS data plane-based source routing paradigm in which the sender of a packet is allowed to partially or completely specify the route the packet takes through the network by imposing stacked MPLS labels on the packet. SR-MPLS can be leveraged to realize a source routing mechanism across MPLS, IPv4, and IPv6 data planes by using an MPLS label stack as a source routing instruction set while making no changes to SR-MPLS specifications and interworking with SR-MPLS implementations. This document describes how SR-MPLS capable routers and IP-only routers can seamlessly co-exist and interoperate through the use of SR-MPLS label stacks and IP encapsulation/tunneling such as MPLS-in- UDP as defined in RFC 7510.

[See also my response to Mirja] I think this wibbliness may be due to a disagreement about whether it = was even necessary to specify how the FIB was constructed since the = process is just SR as usual. But (of course) we have the text and we = must get it right. Your suggestion is the right way forward. That is, text that is generic = and definitive (the main Section 3.1), and more detailed text that is = the examples currently present with the 2119 language removed (moved = into 3.1.1). > (2) Tunnel Endpoints > > =C2=A72: "The tunnel selected MUST have its remote end point = (destination) address > equal to the address of the next SR-MPLS capable node along the path = (i.e., the > egress of the active node segment)." I find this statement misleading = and > confusing. Confusing is not good. > In the general case the statement is wrong: Yes, the tunnel = destination should > be the next SR-MPLS node, but that isn't always "the egress of the = active node > segment". For example, in Figure 2 the SID could direct the traffic = to the > Egress Router (e.g. using it's Node SID) while having individual = tunnels from > the Ingress Router to the first SR, then to the next SR, etc., as = explained in > =C2=A73.2.1/3.2.2. OK.=20 This is a little more complicated than it appears. When the tunnel ends, the revealed packet will be an MPLS-SR packet, so = it is clearly important that the tunnel can only end at an SR-MPLS = capable node. Now, the tunnel ingress must know the identity of the egress. That is, = to tunnel you have to tunnel to somewhere. There are two ways the tunnel ingress can do this: - by extracting that information from the SID stack - by learning from a routing protocol The latter could be done by building an overlay topology map from the = IGP information that identifies the SR-capable nodes. But this would = also need some smarts because otherwise you would end up with a full = mesh of tunnels. A better way of achieving it for the case in figure 1 = would be using a VPN-like solution such as that described in = draft-ietf-bess-datacenter-gateway. But what we have chosen to do is focus on the case where the tunnel = targets the next node in the SID stack. If you think about it, even in = the case for figure 1, the remote site might be dual homed and it will = be important to select the correct entry point, a feature that is only = made possible by directing the tunnel (possibly based on routing = information as suggested in draft-ietf-bess-datacenter-gateway) to the = correct entry point since otherwise the IP-enabled connecting network = will just use a shortest path approach. This means that there can be a variety of nodes on the packet's path as = explained in Section 3.2. There are six types of node and one of them = is: | o Transit nodes that are SR-MPLS capable but that are not identified | by a SID in the SID stack. Thus you are right that the text needs to be fixed. It really should be "The next SR-MPLS-capable node identified as being = on the SR path." That is, "The egress of the active node segment" in all = cases. > I realize that the sentence after the statement above is "This is = shown in > Figure 1." Figure 1 is a degenerate case of the (almost) general case = from > Figure 2. Even in the single tunnel (Figure 1) case, "the egress of = the active > node segment" doesn't have to be R2, it could be another node inside = the > SR-MPLS network (as R2, being SR-MPLS aware, should be able to forward = the > frames). No, I don't think it can. While I understand that you *could* tunnel to R2 for a segment that ends = beyond R2, I don't see how you would know to make/use that tunnel unless = there was some programming at R1 to tell it that. (See the discussion = above). And, in summary, this is not the solution we have documented. > 1. It is wrong. I think that what makes it wrong is the clarification = that > "the next SR-MPLS capable node along the path" is "the egress of the = active > node segment". Taken the text is parenthesis out would solve this = issue. As above, it will now read: The tunnel selected MUST have its remote end point (destination) address equal to the address of the next SR-MPLS capable node = identified as being on the SR path (i.e., the egress of the active node = segment). > 2. It is a general statement. The placement is somewhat unfortunate = because > it seems that it may apply only to the Figure 1 case...but it applies = in > general...and there is no similar statement then describing other = cases.=20 >=20 > Instead of adding something similar for Figure 2, perhaps move the = sentence > to a place that covers all the use cases. You're right, it applies to all tunnelling cases and the text can be = dragged up above the bullet list. > A third issue with the statement comes up when considering = =C2=A73.1/=C2=A73.2: > there is no specification there that explains how to figure out which > should be the tunnel destination address. The example in =C2=A73.1 = only > talks about receiving information from E, including the "the = encapsulation > endpoint and the tunnel type of any tunnel used to reach E"...but says > nothing about other potential SR-MPLS capable nodes between A and E, > or how A would use a tunnel to one of those transit nodes on the way = to > E...which is what is illustrated in =C2=A73.2.1/3.2.2. It isn't the intention of this document to provide a full soup/nuts = solution kit. It is much more an observation that 7510 can be used to = achieve the function required. Earlier revisions had more information on the possible control plane = mechanisms that could be combined with the data plane encapsulations.=20 For now, we content ourselves with pointers to a number of control plane = drafts. We have added draft-ietf-bess-datacenter-gateway to that list. > (3) A very, very late IPR declaration came in after the IETF LC = started. > I didn't find a thread where the WG was made aware of it. > > https://datatracker.ietf.org/ipr/3439/ I hope my previous email (mid-April) on this addressed your concerns. > COMMENT: I hope my previous email (mid-April) on this addressed your concerns.

Hi Huub, Thank you for your review and comments. Please see zzh> below. Non-Juniper From: Huub van Helvoort Sent: Monday, April 8, 2019 5:58 AM To: mpls@ietf.org Cc: draft-zzhang-mpls-rmr-multicast@ietf.org; mpls-chairs@ietf.org Subject: MPLS-RT review of draft-zzhang-mpls-rmr-multicast All, I=92ve been selected as an MPLS-RT reviewer for draft-zzhang-mpls-rmr-multi= cast, which is currently a candidate for MPLS WG adoption. In the abstract is stated: With Resilient MPLS Rings (RMR), although all existing multicast procedures and solutions can work as is, there are optimizations that could be done for RSVP-TE P2MP tunnel signaling and Fast-ReRouting for both mLDP and RSVP-TE P2MP tunnels. I have carefully read the draft but I could not find any justification for the optimisation that could be done. Zzh> By =93justification", do you mean =93need=94? I thought the following = text provides that: For a conventionally signaled RSVP-TE P2MP tunnel, an ingress LSR discovers leaves and signals one sub-LSP for each leaf. Even though the forwarding state is merged at each hop (i.e, one incoming label mapping to multiple outgoing entries), the control plane maintains individual sub-LSP state. This leads to lots of redundant state on routers close to the ingress. [hvh] "lots of state" - can you be more specific? is the redundancy 10% or = 90% ? Zzh2> Depending on how many leaves you have. With traditional RSVP-TE P2MP,= there is one sub-LSP to each leaf. If you have 20 leaves, the saving is 95= % (I mean you only need to maintain 5% of state compared to traditional way= ). If you have 10 leaves, the saving is 90%. I don=92t think the draft need= s to quantify it. [hvh-2] the draft should mention it because it may be a reason to apply the optimization or not. [hvh-2] if a leave is deleted, added, or changed all leaves will be notifie= d and will have to process the notification. Zzh> Or do you mean =93why=94 the optimization COULD be done? The key is th= at this is a ring, and: =85 As the PATH message passes along the ring, the leaves send RESV messages, but only one RESV message reaches the tunnel ingress. [hvh] can you explain why only one RESV message reaches the tunnel ingress? Zzh2> Because only one PATH message is sent, and the RESV state gets merged= accordingly along the way. [hvh-2] the merging requires processing resources. Zzh> If you mean =93how=94 it is done, I thought the following describes i= t: =85 With RMR, this can be optimized such that only a single LSP is signaled, with all the leaves listed in the PATH message. As the PATH message passes along the ring, the leaves send RESV messages, but only one RESV message reaches the tunnel ingress. The ingress LSR may also send PATH messages in both directions, so that the tunnel is set up in such a way that minimum delay is incurred for traffic to reach all leaves. Alternatively, the ingress may send PATH message only in one direction for best bandwidth utilization. For example, a leaf D is three hops away from the ingress A in clockwise direction (A,B,C,D) and four hops away in the other direction (A,E,F,G,D), but G is also a leaf so it may be better to just send the PATH message in the anticlockwise direction. Each router establishes forwarding state accordingly. Transit routers switches traffic towards downstream. A transit router could also be a leaf router and in that case it does "drop and continue" - sends traffic off the ring and switches traffic downstream. 2.1. Tunnel Protection and FRR Each node on a ring signals two counter-rotating MP2P RSVP-TE LSPs to itself. As these LSPs are self-signaled after the discovery of the ring, they can be used to protect P2MP LSPs on ring. So neither mLDP nor RSVP-TE has to setup a separate P2P bypass LSPs for link and node protection. [hvh] This is clear. I also did not find any indication how this optimisation has to be deployed. Do all the nodes in the ring, or in the network have to support this optimisation before it becomes effective. Zzh> The context is RMR =96 Resilient MPLS Ring. All routers on the ring ne= ed to support RMR and the multicast optimization for this to be effective. = I can make that clear. [hvh] OK. Thanks. I think these issues have to be documented before this draft can be adopted as WG draft. Zzh> Besides explicitly stating that all routers on the ring need to suppor= t the RSVP-TE P2MP optimization for it to be effective, please advise furth= er how the first issue can be better documented. [hvh] when you use the word "optimize" I expect an indication of the effect of the optimization on performance, or used resources. Zzh2> I see. The optimization is on (simpler) procedures and (less) resourc= es. I don=92t think we need to quantify it. [hvh-2] I would like to know why I should deploy this "optimisation", and maybe others would like to know too. Zzh2> I will update the draft to point out that all routers on the ring nee= ds to support the optimization =96 please let me know if that is enough. Zzh2> Thanks!

Hi Huub, Tarek,

 

Based on your comments, I removed the text about RSVP= -TE P2MP tunnel optimization and simply refer to the other document. Hope t= his will address your concerns.

Subject: MPLS-RT review of draft-zzhang-mpls-rmr-multicast

 

All,

 

I=92ve been selected as a= n MPLS-RT reviewer for draft-zzhang-mpls-rmr-multicast,
which is currently a candidate for MPLS WG adoption.

 

In the abstract is stated= :

   With Resilient MPLS Rings (RMR=
), although all existing multicast
   procedures and solutions can w=
ork as is, there are optimizations that
   could be done for RSVP-TE P2MP=
 tunnel signaling and Fast-ReRouting
   for both mLDP and RSVP-TE P2MP=
 tunnels.

I have carefully read the= draft but I could not find any justification
for the optimisation that could be done.

 

Zzh> By =93justification", do you mean =93need=94? I though= t the following text provides that:

 

   For a conventionally signaled RSVP-TE P2MP tunnel, an = ingress LSR

   discovers leaves and signals one sub-LSP for each leaf= .  Even though

   the forwarding state is merged at each hop (i.e, one i= ncoming label

   mapping to multiple outgoing entries), the control pla= ne maintains

   individual sub-LSP state.  This leads to lots of = redundant state on

   routers close to the ingress.

[hvh] "lots of state" - can you be more specific? is the redundan= cy 10% or 90% ?

Zzh2> Depending on how many leaves you have. With traditional RS= VP-TE P2MP, there is one sub-LSP to each leaf. If you have 20 leaves, the s= aving is 95% (I mean you only need to maintain 5% of state compared to traditional way). If you have 10 leaves, the savin= g is 90%. I don=92t think the draft needs to quantify it.=

[hvh-2] the draft should mention it because it may be a reason to apply the=
optimization or not.

[hvh-2] if a leave is deleted, added, or changed all leaves will be notifie= d and will
have to process the notification.

Zzh> Or do you mean =93why=94 the optimization COULD be done? Th= e key is that this is a ring, and:

 

   =85 As the PATH message passes along the ring, the lea= ves

   send RESV messages, but only one RESV message reaches = the tunnel

   ingress.

[hvh] can you explain why only one RESV message reaches the tunnel ingress?=

Zzh2> Because only one PATH message is sent, and the RESV state = gets merged accordingly along the way.

[hvh-2] the merging requires processing resources.

 Zzh> If you mean =93how=94 it is done, I thought the follo= wing describes it:

 

   =85 With RMR, this can be optimized such

   that only a single LSP is signaled, with all the leave= s listed in the

   PATH message.  As the PATH message passes along t= he ring, the leaves

   send RESV messages, but only one RESV message reaches = the tunnel

   ingress.

 

   The ingress LSR may also send PATH messages in both di= rections, so

   that the tunnel is set up in such a way that minimum d= elay is

   incurred for traffic to reach all leaves.  Altern= atively, the ingress

   may send PATH message only in one direction for best b= andwidth

   utilization.  For example, a leaf D is three hops= away from the

   ingress A in clockwise direction (A,B,C,D) and four ho= ps away in the

   other direction (A,E,F,G,D), but G is also a leaf so i= t may be better

   to just send the PATH message in the anticlockwise dir= ection.

 

   Each router establishes forwarding state accordingly.&= nbsp; Transit

   routers switches traffic towards downstream.  A t= ransit router could

   also be a leaf router and in that case it does "d= rop and continue" -

   sends traffic off the ring and switches traffic downst= ream.

 

2.1.  Tunnel Protection and FRR

 

   Each node on a ring signals two counter-rotating MP2P = RSVP-TE LSPs to

   itself.  As these LSPs are self-signaled after th= e discovery of the

   ring, they can be used to protect P2MP LSPs on ring.&n= bsp; So neither mLDP

   nor RSVP-TE has to setup a separate P2P bypass LSPs fo= r link and node

   protection.

[hvh]  This is clear.

I also did not find any i= ndication how this optimisation has to be
deployed. Do all the nodes in the ring, or in the network have to
support this optimisation before it becomes effective.

 

Zzh> The context is RMR =96 Resilient MPLS Ring. All routers on = the ring need to support RMR and the multicast optimization for this to be = effective. I can make that clear.

[hvh] OK. Thanks.

 I think these issue= s have to be documented before this draft can

be adopted as WG draft.

 

Zzh> Besides explicitly stating that all routers on the ring nee= d to support the RSVP-TE P2MP optimization for it to be effective, please a= dvise further how the first issue can be better documented.

[hvh] when you use the wo= rd "optimize" I expect an indication of
the effect of the optimization on performance, or used resources.

 

Zzh2> I see. The optimization is on (simpler) procedures and (le= ss) resources. I don=92t think we need to quantify it.

[hvh-2] I would like to know why I should deploy this "optimisation&qu= ot;,
and maybe others would like to know too.

Zzh2> I will update the draft to point out that all routers on t= he ring needs to support the optimization =96 please let me know if that is= enough.

Zzh2> Thanks!

Zzh2> Jeffrey

Best regards, Huub.

Hi Alexander,

I beleive MTU handling post FRR is not covered in base = RFC4090 and is therefore an existing gap.
It kinda defeats the purpose if headend needs to adjust = MTU after FRR to prevent drops=E2=80=A6 and would presume most = deployments assume that backup MTU can accomandate MTU of primary LSP = (plus any added MP labels). 

Issue deserves discussion, but think its out of scope = from this document.

Hi Mike,

If we don't talk about gap in procedure of Path messages = merging by MP, then I don't see other gaps in RFC 4090. But I see that = gap with MTU adjusting appears with introduction of Summary = FRR.

Current = behavior is follow:

1) PLR sends backup LSP Path to MP with actual MTU in = ADSPEC;
2) MP sends backup LSP Resv to PLR with = actual MTU in FLOWSPEC (derived from ADSPEC);
3) = PLR merges FLOWSPECs of protected and backup Resv messages (according to = RFC 2210) and sends Resv upstream with actual MTU in FLOWSPEC.

New behavior with = Summary FRR:

1) = PLR sends SFRR-Active Path to MP;
2) MP does = summary refresh for backup LSPs;
3) PLR sends Resv = with unchanged MTU of protected LSP upstream, as before failure. This is = because FLOWSPEC for backup LSP has not been updated, and resulting = FLOWSPEC thus has not been updated.

I cannot agree that head-end not need = to be aware about path MTU changes. If head-end is irrespective to = actual path MTU, it could cause blackholing of packets that are larger = than actual path MTU. Also, I'm not aware about implementations of PLR = that take into account MTU in SENDER_TSPEC of protected LSPs and choose = bypass tunnels accordingly. My knowledge that many of them agnostic to = this.

Thank = you.

Hi Alexander

By gap, I mean its not mentioned/covered at all.

To give alternate perspective, I disagree with trying to = merge state of primary and backup LSP.
And would think it unncessary for either the MP or the = headend to be aware, or make any MTU changes post FRR.

I do agree with your last statement where PLR should = ensure the MTU of backup can accomdate the primary LSP MTU (plus any = encap added to transport over the backup LSP).
And surely most implementations are already doing this, = or FRR wouldn=E2=80=99t be that successful...

Do you not agree this issue/gap is out of scope of (ie. = not specific to ) this document ?

I agree that guaranting enough MTU size on all links in = the network is good practice, but in reality it not always could be = provided, or could be provided with significant penalty on = manageability.

Per my understanding, reliable solution would be for = head-end:

1) to specify minimum LSP MTU as a constraint (like = resource affinities, BW, etc.) for CSPF and take link MTUs from TEDB = into consideration, and

2) to signal to downstream LSRs minimum LSP MTU (by = virtue of SENDER_TSPEC, like BW), such that PLRs would be able to make = decision about availability of bypass tunnels, which can accomodate = requested MTU.

Thank you!

Hi Alexander,

I beleive MTU handling post FRR is not covered in base = RFC4090 and is therefore an existing gap.
It kinda defeats the purpose if headend needs to adjust = MTU after FRR to prevent drops=E2=80=A6 and would presume most = deployments assume that backup MTU can accomandate MTU of primary LSP = (plus any added MP labels). 

Issue deserves discussion, but think its out of scope = from this document.

For example, = path MTU of protected LSP is 1500 bytes (provided that ADSPEC is used), and path MTU of bypass tunnel is, for example, = 1500 bytes. As far as Path messages for protected LSPs are not being = sent over bypass tunnel, MP will use ADSPEC received in Path messages of = those protected LSPs previoulsy (before they have been rerouted onto bypass tunnel), i.e. 1500 bytes in place of = 1496 bytes. To avoid this problem PLR would have to signal path MTU of = its bypass tunnel in B-SFRR-Active object (alternatively, MP could = inherit this value from ADSPEC of PSB of the bypass tunnel), and 2) MP would have to choose minimal of MTU values from = ADSPEC objects while merging Summary FRR protected LSP. But, even in = this case MP will have to generate trigger Path messages (with updated = ADSPEC) for protected LSPs and then, after receiving Resv messages with updated FLOWSPEC, send them to PLR. I.e. summary = refresh in MP->PLR direction with high probability will be = inapplicable, due to trigger messages.

Thanks.

Please read this document if you haven't = read the most recent version yet, and send your comments to the mpls wg = mailing list (mpls@ietf.org), not later than 17th of May.
 
There is one IPR disclosure against draft-ietf-mpls-summary-frr-rsvpte
 
This working group last call ends May = 17th, 2019 (there is at least in some countries a public holiday this = week, therefore the call is a bit longer than usual).
 
Best regards

Yes, I'm fine with proposed update. I have some comments regarding choosing address for RSVP_HOP and = SENDER_TEMPLATE on PLR and MP. 1) The draft doesn't say that PLR should choose the same Sender address = for SENDER_TEMPLATE of backup LSPs as chosen one for corresponding = bypass tunnel. Hence it could be that two will be different. It will = cause to use different sender address for SENDER_TEMPLATE by PLR and MP. 2) The draft doesn't say that address in RSVP_HOP for backup LSPs and = address in SENDER_TEMPLATE for corresponding bypass tunnel should be = different. Hence, it could be that addresses in RSVP_HOP of SFRR-Active = and in SENDER_TEMPLATE of bypass tunnel are the same. In case when PLR = is head-end, it could pose problem for MP in part of choosing sender = address for SENDER_TEMPLATE of backup LSP. It could be presumed that = address for RSVP_HOP in SFRR-Active is taken from egress transit = interface for originated bypass tunnel, and address for SENDER_TEMPLATE = of bypass tunnel is loopback address of PLR, and thus they will be = different. But in case of unnumbered interface on PLR, that is used as = egress by bypass tunnel, election of address for RSVP_HOP is not so = straightforward. It could be well possible that for RSVP_HOP of backup = LSPs the same loopback address of PLR will be chosen as for = SENDER_TEMPLATE of bypass tunnel. Also, RFC 4090 doesn't prescribe how = PLR chooses address for RSVP_HOP. 3) The draft says that all protected LSPs, that share the same egress = link and are protected by the same bypass tunnel, are assigned to the = same bypass group. It is not a problem, if mentioned above = inconsitencies will be addressed. Otherwise, there could be problem, = because, based on current text, all backup LSPs of the same group should = share SENDER_TEMPLATE (i.e. Sender Address in SENDER_TEMPLATE). Though = on MP there will be two groups of backup LSPs in the same bypass group: = that take address for SENDER_TEMPLATE from SENDER_TEMPLATE of bypass = tunnel (transit protected LSP), and that take address for = SENDER_TEMPLATE from RSVP_HOP of SFRR-Active (for protected LSPs = originated on PLR). For the latter SENDER_TEMPLATE on PLR and MP will be = different. 4) The draft says that RSVP_HOP and SENDER_TEMPLATE for backup LSPs of = the same bypass group should be the same. I guess that it should say = that Sender Address in SENDER_TEMPLATE should be common, rather than = SENDER_TEMPLATE itself. SENDER_TEMPLATE will be different for each = backup LSP due to different LSP_IDs.

Hi Tarek,

Thank you for answer. Yes, I'm fine with proposed = update.

I have = some comments regarding choosing address for RSVP_HOP and = SENDER_TEMPLATE on PLR and MP.

1) The draft doesn't say that PLR = should choose the same Sender address for SENDER_TEMPLATE of backup LSPs = as chosen one for corresponding bypass tunnel. Hence it could be that = two will be different. It will cause to use different sender address for = SENDER_TEMPLATE by PLR and MP.

2) The draft doesn't say that address = in RSVP_HOP for backup LSPs and address in SENDER_TEMPLATE for = corresponding bypass tunnel should be different. Hence, it could be that = addresses in RSVP_HOP of SFRR-Active and in SENDER_TEMPLATE of bypass = tunnel are the same. In case when PLR is head-end, it could pose problem = for MP in part of choosing sender address for SENDER_TEMPLATE of backup = LSP. It could be presumed that address for RSVP_HOP in SFRR-Active is = taken from egress transit interface for originated bypass tunnel, and = address for SENDER_TEMPLATE of bypass tunnel is loopback address of PLR, = and thus they will be different. But in case of unnumbered interface on = PLR, that is used as egress by bypass tunnel, election of address for = RSVP_HOP is not so straightforward. It could be well possible that for = RSVP_HOP of backup LSPs the same loopback address of PLR will be chosen = as for SENDER_TEMPLATE of bypass tunnel. Also, RFC 4090 doesn't = prescribe how PLR chooses address for RSVP_HOP.

3) The draft says that all protected = LSPs, that share the same egress link and are protected by the same = bypass tunnel, are assigned to the same bypass group. It is not a = problem, if mentioned above inconsitencies will be addressed. Otherwise, = there could be problem, because, based on current text, all backup LSPs = of the same group should share SENDER_TEMPLATE (i.e. Sender Address in = SENDER_TEMPLATE). Though on MP there will be two groups of backup LSPs = in the same bypass group: that take address for SENDER_TEMPLATE from = SENDER_TEMPLATE of bypass tunnel (transit protected LSP), and that take = address for SENDER_TEMPLATE from RSVP_HOP of SFRR-Active (for protected = LSPs originated on PLR). For the latter SENDER_TEMPLATE on PLR and MP = will be different.

4) The draft says that RSVP_HOP and SENDER_TEMPLATE for = backup LSPs of the same bypass group should be the same. I guess that it = should say that Sender Address in SENDER_TEMPLATE should be common, = rather than SENDER_TEMPLATE itself. SENDER_TEMPLATE will be different = for each backup LSP due to different LSP_IDs.

Hence, I would like to see details of = choosing addresses for RSVP_HOP and SENDER_TEMPLATE of backup LSPs to be = cleaned. Also, I think that it would be better to signal Sender Address = for backup LSPs in SFRR-Active explicitly, rather than derive it by MP = indirectly from SENDER_TEMPLATE of bypass tunnel.
Thank you.

Hi Alexander,
 
Thanks for your = suggestions and comments. We discussed this further amongst authors. We = think the PLR has to do a proactive check of the MTU on the bypass = tunnel for proper FRR to work correctly at all times.
We will introduce an addition in = section 3.3.1 of the I-D to describe this:
 
=E2=80=9CWhen = using procedures defined in this document, the PLR MUST ensure bypass = tunnel assignment can satisfy the protected LSP MTU requirements post = FRR. This is to avoid any packets from getting dropped due to exceeding = the MTU size of the bypass tunnel after FRR.=E2=80=9D
 
Let us know if = this addresses your concerns.

Tarek

Hi Mike,
 
If we don't talk about gap in procedure of Path = messages merging by MP, then I don't see other gaps in RFC 4090. But I = see that gap with MTU adjusting appears with introduction of Summary = FRR.
 
Current behavior is follow:
 
1) PLR sends backup LSP Path to MP with = actual MTU in ADSPEC;
2) MP sends backup = LSP Resv to PLR with actual MTU in FLOWSPEC (derived from ADSPEC);
3) PLR merges FLOWSPECs of protected and backup Resv messages = (according to RFC 2210) and sends Resv upstream with actual MTU in = FLOWSPEC.
 
New behavior with Summary FRR:
 
1) PLR sends SFRR-Active Path to = MP;
2) MP does summary refresh for backup LSPs;
3) PLR sends Resv with unchanged MTU of protected LSP = upstream, as before failure. This is because FLOWSPEC for backup LSP has = not been updated, and resulting FLOWSPEC thus has not been updated.
 
I cannot agree that head-end not need = to be aware about path MTU changes. If head-end is irrespective to = actual path MTU, it could cause blackholing of packets that are larger = than actual path MTU. Also, I'm not aware about implementations of PLR = that take into account MTU in SENDER_TSPEC of protected LSPs and choose = bypass tunnels accordingly. My knowledge that many of them agnostic to = this.
 
Thank you.

Hi = Alexander 
 
By gap, I mean its not = mentioned/covered at all.
 
To give alternate perspective, I disagree with = trying to merge state of primary and backup LSP.
And would think it unncessary for either the MP or the = headend to be aware, or make any MTU changes post FRR.
 
I do agree with your last statement = where PLR should ensure the MTU of backup can accomdate the primary LSP = MTU (plus any encap added to transport over the backup LSP).
And surely most implementations are already doing this, or = FRR wouldn=E2=80=99t be that successful...
 
Do you not agree this issue/gap is out = of scope of (ie. not specific to ) this document ?

Per my understanding, reliable solution would be = for head-end:

2) to signal to downstream LSRs minimum LSP MTU = (by virtue of SENDER_TSPEC, like BW), such that PLRs would be able to = make decision about availability of bypass tunnels, which can accomodate = requested MTU.

Hi Alexander, 
 
I beleive MTU handling post FRR is not = covered in base RFC4090 and is therefore an existing gap.
It kinda defeats the purpose if headend needs to adjust MTU = after FRR to prevent drops=E2=80=A6 and would presume most deployments = assume that backup MTU can accomandate MTU of primary LSP (plus any = added MP labels). 
 
Issue deserves discussion, but think its out of = scope from this document.

Hi Tarek,

Thank you for answer. Yes, I'm fine with proposed update.

I have some comments regardin= g choosing address for RSVP_HOP and SENDER_TEMPLATE on PLR and MP.

1) The draft doesn't say th= at PLR should choose the same Sender address for SENDER_TEMPLATE of backup L= SPs as chosen one for corresponding bypass tunnel. Hence it could be that tw= o will be different. It will cause to use different sender address for SENDE= R_TEMPLATE by PLR and MP.

2) The draft doesn't say that address in RSVP_HOP for backup LSPs an= d address in SENDER_TEMPLATE for corresponding bypass tunnel should be diffe= rent. Hence, it could be that addresses in RSVP_HOP of SFRR-Active and in SE= NDER_TEMPLATE of bypass tunnel are the same. In case when PLR is head-end, i= t could pose problem for MP in part of choosing sender address for SENDER_TE= MPLATE of backup LSP. It could be presumed that address for RSVP_HOP in SFRR= -Active is taken from egress transit interface for originated bypass tunnel,= and address for SENDER_TEMPLATE of bypass tunnel is loopback address of PLR= , and thus they will be different. But in case of unnumbered interface on PL= R, that is used as egress by bypass tunnel, election of address for RSVP_HOP= is not so straightforward. It could be well possible that for RSVP_HOP of b= ackup LSPs the same loopback address of PLR will be chosen as for SENDER_TEM= PLATE of bypass tunnel. Also, RFC 4090 doesn't prescribe how PLR chooses add= ress for RSVP_HOP.

3) The draft says that all protected LSPs, that share the same egress link a= nd are protected by the same bypass tunnel, are assigned to the same bypass g= roup. It is not a problem, if mentioned above inconsitencies will be address= ed. Otherwise, there could be problem, because, based on current text, all b= ackup LSPs of the same group should share SENDER_TEMPLATE (i.e. Sender Addre= ss in SENDER_TEMPLATE). Though on MP there will be two groups of backup LSPs= in the same bypass group: that take address for SENDER_TEMPLATE from SENDER= _TEMPLATE of bypass tunnel (transit protected LSP), and that take address fo= r SENDER_TEMPLATE from RSVP_HOP of SFRR-Active (for protected LSPs originate= d on PLR). For the latter SENDER_TEMPLATE on PLR and MP will be different.

4) The draft says t= hat RSVP_HOP and SENDER_TEMPLATE for backup LSPs of the same bypass group sh= ould be the same. I guess that it should say that Sender Address in SENDER_T= EMPLATE should be common, rather than SENDER_TEMPLATE itself. SENDER_TEMPLAT= E will be different for each backup LSP due to different LSP_IDs.

Hence, I would like to see de= tails of choosing addresses for RSVP_HOP and SENDER_TEMPLATE of backup LSPs t= o be cleaned. Also, I think that it would be better to signal Sender Address= for backup LSPs in SFRR-Active explicitly, rather than derive it by MP indi= rectly from SENDER_TEMPLATE of bypass tunnel.

Thank you.

Hi Alexander,
 
Thanks for your suggest= ions and comments. We discussed this further amongst authors. We think the P= LR has to do a proactive check of the MTU on the bypass tunnel for proper FR= R to work correctly at all times.
We will intro= duce an addition in section 3.3.1 of the I-D to describe this:
 
=E2=80=9CWhen using proc= edures defined in this document, the PLR MUST ensure bypass tunnel assignmen= t can satisfy the protected LSP MTU requirements post FRR. This is to avoid a= ny packets from getting dropped due to exceeding the MTU size of the bypass t= unnel after FRR.=E2=80=9D
 =
Let us know if this addresses your concerns.
 
Regards,=
Tarek

Hi Mike,
 
=
If we don't talk abou= t gap in procedure of Path messages merging by MP, then I don't see other ga= ps in RFC 4090. But I see that gap with MTU adjusting appears with introduct= ion of Summary FRR.
 
Current behavior is follow:
 
1) PLR sends backup LSP Path to MP with actual MTU in ADSPEC;
2) MP sends backup LSP Resv to PLR with actual MTU in FLOWSPEC (derived fro= m ADSPEC);
3) PLR merges FLOWSPECs of protected and backup Resv messag= es (according to RFC 2210) and sends Resv upstream with actual MTU in FLOWSP= EC.
 
New behavior with Summary FRR:<= /div>
=  
1) P= LR sends SFRR-Active Path to MP;
2) MP does summary refresh for backup= LSPs;
3) PLR sends Resv with unchanged MTU of protected LSP upstream,= as before failure. This is because FLOWSPEC for backup LSP has not been upd= ated, and resulting FLOWSPEC thus has not been updated.
 
I= cannot agree that head-end not need to be aware about path MTU changes. If h= ead-end is irrespective to actual path MTU, it could cause blackholing of pa= ckets that are larger than actual path MTU. Also, I'm not aware about implem= entations of PLR that take into account MTU in SENDER_TSPEC of protected LSP= s and choose bypass tunnels accordingly. My knowledge that many of them agno= stic to this.

Hi Alexander 
 
=
By gap, I mean its not ment= ioned/covered at all.
 
To give alternate perspective, I dis= agree with trying to merge state of primary and backup LSP.<= /o:p>
And would t= hink it unncessary for either the MP or the headend to be aware, or make any= MTU changes post FRR.
 
I do agree with your last statemen= t where PLR should ensure the MTU of backup can accomdate the primary LSP MT= U (plus any encap added to transport over the backup LSP).
And surely m= ost implementations are already doing this, or FRR wouldn=E2=80=99t be that s= uccessful...

Hi Mike,
 
Do you mean the gap in merging of Path m= essages by MP in part of choosing ADSPEC of protected LSP rather than mergin= g ADSPECs (choosing minimal MTU, particularly)? Oh, agree. Though if we woul= d assume that MP did perform merging of ADSPEC (and probably other objects w= here applicable), there would be problem with signaling backup LSP MTU to MP= after failure.

I agree that guaranting enough MTU size on a= ll links in the network is good practice, but in reality it not always could= be provided, or could be provided with significant penalty on manageability= .
 
Per my understanding, reliable solution would be for hea= d-end:
 
1) to specify minimum LSP MTU as a constraint (lik= e resource affinities, BW, etc.) for CSPF and take link MTUs from TEDB into c= onsideration, and
 
2) to signal to downstream LSRs minimum L= SP MTU (by virtue of SENDER_TSPEC, like BW), such that PLRs would be able to= make decision about availability of bypass tunnels, which can accomodate re= quested MTU.

Hi Alexande= r, <= /div>
 =
I beleive= MTU handling post FRR is not covered in base RFC4090 and is therefore an ex= isting gap.
It kinda defeats the purpose if headend needs to adjust MT= U after FRR to prevent drops=E2=80=A6 and would presume most deployments ass= ume that backup MTU can accomandate MTU of primary LSP (plus any added MP la= bels).

Hi authors,
 
= As far as Summary FRR LSPs are not being signaled via Path messages over byp= ass tunnel after failure, information on head-ends about actual path MTU of p= rotected LSPs can be corrupted. For example, path MTU of protected LSP is 15= 00 bytes (provided that ADSPEC is used), and path MTU of bypass tunnel is, f= or example, 1500 bytes. As far as Path messages for protected LSPs are not b= eing sent over bypass tunnel, MP will use ADSPEC received in Path messages o= f those protected LSPs previoulsy (before they have been rerouted onto bypas= s tunnel), i.e. 1500 bytes in place of 1496 bytes. To avoid this problem PLR= would have to signal path MTU of its bypass tunnel in B-SFRR-Active object (= alternatively, MP could inherit this value from ADSPEC of PSB of the bypass t= unnel), and 2) MP would have to choose minimal of MTU values from ADSPEC obj= ects while merging Summary FRR protected LSP. But, even in this case MP will= have to generate trigger Path messages (with updated ADSPEC) for protected L= SPs and then, after receiving Resv messages with updated FLOWSPEC, send them= to PLR. I.e. summary refresh in MP->PLR direction with high probability w= ill be inapplicable, due to trigger messages.
 
Thanks.

These days most SP have thei= r optical mesh network but with LAN PHY Ethernet handoff from Ethernet over S= onet and not WAN phy OC handoff you would not terminate 4 fiber connect an S= P router via OCx so would not sit on sonet ring or any ring topology so woul= d their be a need for RMR for optical ring topologies.

Loa and the WG,
As one of the co-authors, I support pr= ogressing this draft.
From my POV, the need for it has been demon= strated at the last EANTC event where we have, for the 2nd time in a row, e= xperienced the very interoperability issue that this draft is supposed to e= liminate.

At the same time, I would like to remind= all that, as part of the WG adoption call we have agreed to add the follow= ing text at the end of Section 4 after adoption of the draft (see=C2=A0https://mailarchive.ietf.org/arch/= msg/mpls/yMQIR8Zadkx6X9faDnIwj-s8mW4):

"The Figures in Se= ctions 4.1, 4.2, and 4.3 replace the corresponding
Figures in RFC 8029= =C2=A0 Sections 5.1, 5.2, and 5.3 respectively. The
updated figures cont= ain explicitly defined length."

From my POV this should be done= before the draft is sent to the IESG.

Regards,
Sasha Vainshtein

Contreras Filename : draft-ietf-mpls-rmr-10.txt Pages : 15 Date : 2019-05-21 Abstract: This document describes the use of the MPLS control and data planes on ring topologies. It describes the special nature of rings, and proceeds to show how MPLS can be effectively used in such topologies. It describes how MPLS rings are configured, auto-discovered and signaled, as well as how the data plane works. Companion documents describe the details of discovery and signaling for specific protocols.

This draft is a work item of the Multiprotocol Label Switching WG of the IETF. Title : RSVP-TE Summary Fast Reroute Extensions for LSP Tunnels Authors : Mike Taillon Tarek Saad Rakesh Gandhi Abhishek Deshmukh Markus Jork Vishnu Pavan Beeram Filename : draft-ietf-mpls-summary-frr-rsvpte-04.txt Pages : 19 Date : 2019-05-22 Abstract: This document defines Resource Reservation Protocol (RSVP) Traffic- Engineering (TE) signaling extensions that reduce the amount of RSVP signaling required for Fast Reroute (FRR) procedures and subsequently improve the scalability of the RSVP-TE signaling when undergoing FRR convergence after a link or node failure. Such extensions allow the RSVP message exchange between the Point of Local Repair (PLR) and the Merge Point (MP) to be independent of the number of protected Label Switched Paths (LSPs) traversing between them when facility bypass FRR protection is used. The signaling extensions are fully backwards compatible with nodes that do not support them.

Sorry for the long delay... ... > (1) Forwarding Entries ... Your suggestion is the right way forward. That is, text that is generic and definitive (the main Section 3.1), and more detailed text that is the examples currently present with the 2119 language removed (moved into 3.1.1). I looked at -05, and the text there works for me. Just one detail (non-blocking): the third step (=C2=A73.1) says "If A and E= are in different IGP domains=E2=80=A6=E2=80=9D. Strictly speaking, specially be= cause we could be dealing with BGP, that should be =E2=80=9Cdifferent routing domains=E2= =80=9D =E2=80=94 while most of the time different autonomous systems, even under the same administration, will use different IGP domains, that is not always the case.

This draft is a work item of the Multiprotocol Label Switching WG of the IETF. Title : SR-MPLS over IP Authors : Xiaohu Xu Stewart Bryant Adrian Farrel Syed Hassan Wim Henderickx Zhenbin Li Filename : draft-ietf-mpls-sr-over-ip-06.txt Pages : 18 Date : 2019-05-23 Abstract: MPLS Segment Routing (SR-MPLS) is an MPLS data plane-based source routing paradigm in which the sender of a packet is allowed to partially or completely specify the route the packet takes through the network by imposing stacked MPLS labels on the packet. SR-MPLS can be leveraged to realize a source routing mechanism across MPLS, IPv4, and IPv6 data planes by using an MPLS label stack as a source routing instruction set while making no changes to SR-MPLS specifications and interworking with SR-MPLS implementations. This document describes how SR-MPLS capable routers and IP-only routers can seamlessly co-exist and interoperate through the use of SR-MPLS label stacks and IP encapsulation/tunneling such as MPLS-in- UDP as defined in RFC 7510.

This draft is a work item of the Multiprotocol Label Switching WG of the IETF. Title : RFC8287 Sub-TLV Length Clarification Authors : Nagendra Kumar Nainar Carlos Pignataro Faisal Iqbal Alexander Vainshtein Filename : draft-ietf-mpls-rfc8287-len-clarification-01.txt Pages : 6 Date : 2019-05-25 Abstract: RFC8287 defines the extensions to MPLS LSP Ping and Traceroute for Segment Routing IGP-Prefix and IGP-Adjacency Segment Identifier (SIDs) with an MPLS data plane. RFC8287 proposes 3 Target FEC Stack Sub-TLVs. While the standard defines the format and procedure to handle those Sub-TLVs, it does not sufficiently clarify how the length of the Segment ID Sub-TLVs should be computed to include in the Length field of the Sub-TLVs which may result in interoperability issues. This document updates RFC8287 by clarifying the length of each Segment ID Sub-TLVs defined in RFC8287. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-mpls-rfc8287-len-clarification/ There are also htmlized versions available at: https://tools.ietf.org/html/draft-ietf-mpls-rfc8287-len-clarification-01 https://datatracker.ietf.org/doc/html/draft-ietf-mpls-rfc8287-len-clarification-01 A diff from the previous version is available at: https://www.ietf.org/rfcdiff?url2=draft-ietf-mpls-rfc8287-len-clarification-01 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.

Please excuse me for the delay.

After re-reviewing the draft I think it is ready for WG adaption.

Best regards, Huub.

Hi Huub, Tarek,

 

Based on your comments, I removed the text about RSVP-TE P2MP tunnel optimization and simply refer to the other document. Hope this will address your concerns.

Subject: MPLS-RT review of draft-zzhang-mpls-rmr-multicast

 

All,

 

I’ve been selected as an MPLS-RT reviewer for draft-zzhang-mpls-rmr-multicast,
which is currently a candidate for MPLS WG adoption.

 

In the abstract is stated:

   With Resilient MPLS Rings (RMR), although all existing multicast
   procedures and solutions can work as is, there are optimizations that
   could be done for RSVP-TE P2MP tunnel signaling and Fast-ReRouting
   for both mLDP and RSVP-TE P2MP tunnels.

I have carefully read the draft but I could not find any justification
for the optimisation that could be done.

 

Zzh> By “justification", do you mean “need”? I thought the following text provides that:

 

   For a conventionally signaled RSVP-TE P2MP tunnel, an ingress LSR

   discovers leaves and signals one sub-LSP for each leaf.  Even though

   the forwarding state is merged at each hop (i.e, one incoming label

   mapping to multiple outgoing entries), the control plane maintains

   individual sub-LSP state.  This leads to lots of redundant state on

   routers close to the ingress.

[hvh] "lots of state" - can you be more specific? is the redundancy 10% or 90% ?

Zzh2> Depending on how many leaves you have. With traditional RSVP-TE P2MP, there is one sub-LSP to each leaf. If you have 20 leaves, the saving is 95% (I mean you only need to maintain 5% of state compared to traditional way). If you have 10 leaves, the saving is 90%. I don’t think the draft needs to quantify it.

[hvh-2] the draft should mention it because it may be a reason to apply the
optimization or not.

[hvh-2] if a leave is deleted, added, or changed all leaves will be notified and will
have to process the notification.


Zzh> Or do you mean “why” the optimization COULD be done? The key is that this is a ring, and:

 

   … As the PATH message passes along the ring, the leaves

   send RESV messages, but only one RESV message reaches the tunnel

   ingress.

[hvh] can you explain why only one RESV message reaches the tunnel ingress?

Zzh2> Because only one PATH message is sent, and the RESV state gets merged accordingly along the way.

[hvh-2] the merging requires processing resources.


 Zzh> If you mean “how” it is done, I thought the following describes it:

 

   … With RMR, this can be optimized such

   that only a single LSP is signaled, with all the leaves listed in the

   PATH message.  As the PATH message passes along the ring, the leaves

   send RESV messages, but only one RESV message reaches the tunnel

   ingress.

 

   The ingress LSR may also send PATH messages in both directions, so

   that the tunnel is set up in such a way that minimum delay is

   incurred for traffic to reach all leaves.  Alternatively, the ingress

   may send PATH message only in one direction for best bandwidth

   utilization.  For example, a leaf D is three hops away from the

   ingress A in clockwise direction (A,B,C,D) and four hops away in the

   other direction (A,E,F,G,D), but G is also a leaf so it may be better

   to just send the PATH message in the anticlockwise direction.

 

   Each router establishes forwarding state accordingly.  Transit

   routers switches traffic towards downstream.  A transit router could

   also be a leaf router and in that case it does "drop and continue" -

   sends traffic off the ring and switches traffic downstream.



2.1.  Tunnel Protection and FRR

 

   Each node on a ring signals two counter-rotating MP2P RSVP-TE LSPs to

   itself.  As these LSPs are self-signaled after the discovery of the

   ring, they can be used to protect P2MP LSPs on ring.  So neither mLDP

   nor RSVP-TE has to setup a separate P2P bypass LSPs for link and node

   protection.

[hvh]  This is clear.


I also did not find any indication how this optimisation has to be
deployed. Do all the nodes in the ring, or in the network have to
support this optimisation before it becomes effective.

 

Zzh> The context is RMR – Resilient MPLS Ring. All routers on the ring need to support RMR and the multicast optimization for this to be effective. I can make that clear.

[hvh] OK. Thanks.


 I think these issues have to be documented before this draft can

be adopted as WG draft.

 

Zzh> Besides explicitly stating that all routers on the ring need to support the RSVP-TE P2MP optimization for it to be effective, please advise further how the first issue can be better documented.

[hvh] when you use the word "optimize" I expect an indication of
the effect of the optimization on performance, or used resources.

 

Zzh2> I see. The optimization is on (simpler) procedures and (less) resources. I don’t think we need to quantify it.

[hvh-2] I would like to know why I should deploy this "optimisation",
and maybe others would like to know too.

Zzh2> I will update the draft to point out that all routers on the ring needs to support the optimization – please let me know if that is enough.

Zzh2> Thanks!

Zzh2> Jeffrey

Best regards, Huub.

This draft is a work item of the Multiprotocol Label Switching WG of the IETF. Title : MPLS Egress Protection Framework Authors : Yimin Shen Minto Jeyananth Bruno Decraene Hannes Gredler Carsten Michel Huaimo Chen Filename : draft-ietf-mpls-egress-protection-framework-05.txt Pages : 28 Date : 2019-05-28 Abstract: This document specifies a fast reroute framework for protecting IP/ MPLS services and MPLS transport tunnels against egress node and egress link failures. For each type of egress failure, it defines the roles of point of local repair (PLR), protector, and backup egress router, and the procedures of establishing a bypass tunnel from a PLR to a protector. It describes the behaviors of these routers in handling an egress failure, including local repair on the PLR, and context based forwarding on the protector. The framework can be used to develop egress protection mechanisms to reduce traffic loss before global repair reacts to an egress failure and control plane protocols converge on the topology changes due to the egress failure.

Notes ----- I am doing some MPLS review. The book I'm using said an LER was an (RFC3031) MPLS edge node. I believed it was any router that could take unlabelled packets and label them, regardless of where the router was within the MPLS domain. (In other words, an MPLS router was not an LER if it would not MPLS label unlabelled packets and forward them.) I decided to check RFC3031 for a definition, and discovered there isn't a definition at all for "label edge router", or a match on any text that matches "label edge" or "LER". RFC6178 clarifies LER processing of IPv4 packets, and the general description of processing matches my understanding of what an LER is. However, it doesn't formally define an "label edge router" either, and I think an update to RFC3031 should be where "label edge router" is formally defined. --VERIFIER NOTES-- This is not an error with RFC3031. It is inappropriate to use an Errata Report to add a new term to an RFC. -------------------------------------- RFC3031 (draft-ietf-mpls-arch-06) -------------------------------------- Title : Multiprotocol Label Switching Architecture Publication Date : January 2001 Author(s) : E.

RFC8287 proposes 3 Target FEC Stack Sub-TLVs.
