This draft is a work item of the Bit Indexed Explicit Replication Working Group of the IETF. Title : Multicast VPN Using BIER Authors : Eric C. Rosen Mahesh Sivakumar IJsbrand Wijnands Sam K Aldrin Andrew Dolganow Tony Przygienda Filename : draft-ietf-bier-mvpn-01.txt Pages : 12 Date : 2015-07-06 Abstract: The Multicast Virtual Private Network (MVPN) specifications require the use of multicast tunnels ("P-tunnels") that traverse a Service Provider's backbone network. The P-tunnels are used for carrying multicast traffic across the backbone. A variety of P-tunnel types are supported. Bit Index Explicit Replication (BIER) is a new architecture that provides optimal multicast forwarding through a "multicast domain", without requiring intermediate routers to maintain any per-flow state or to engage in an explicit tree-building protocol. This document specifies the protocol and procedures that allow MVPN to use BIER as the method of carrying multicast traffic over an SP backbone network. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-bier-mvpn/ There's also a htmlized version available at: https://tools.ietf.org/html/draft-ietf-bier-mvpn-01 A diff from the previous version is available at: https://www.ietf.org/rfcdiff?url2=draft-ietf-bier-mvpn-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.

Or does each egress router have some way of = selecting the ingress router from which it wants to receive a given = flow? Short answer: At this stage of the document, no. Longer answer:=20 Right now, if the same multicast traffic enters the domain at two = different BFIRs, it will be forwarded twice. I guess this could be solve = with a sort of per-flow election mechanism. A router receiving (S,G) = traffic could subscribe to (S,G) within the BIER domain, and therefore = detect when some other BFIR forwards the same flow, and trigger some = assert-like mechanism. Do you expect such situation to happen a lot ?

Does the draft really require that any time a new BFR = is added, all the other BFRs need to be reconfigured? By =E2=80=98configured=E2=80=99 here, I am mostly expecting some kind of = auto-discovery. BFR-ids and BFR-prefixes will be configured as well, by = the mean of the routing protocol, or another protocol (DNCP, from = homenet, could do that for instance). So I think it is reasonable to assume that such ids will be = auto-discoverable and therefore dynamically configured. >=20 > - BFR-ids are only unique within a sub-domain, but the draft doesn't = discuss the role played by sub-domains at all. I must admit I did not consider sub-domains yet. But walking through the architecture draft, I don=E2=80=99t really see = the difference between sub-domains and different domains that happen to = be next to each other. I guess for now, the answer would be to consider that different = instances are run in each subdomain.

That would seem to be a scaling = problem. Yes. This proposal targets implementation simplicity, at the cost of = scalability. I mean, it uses a link-local protocol at a site-local scale, so I = don=E2=80=99t expect it to be very scalable. Of course, proposals to make it more scalable are welcome. >=20 > - Has any thought been given as to whether/how this would work over a = VPN? >=20 If the VPN transports BIER encapsulated packets, I guess it would not be = a problem.

There is nothing unusual about that situation; even if it were unusual, it would still have to be handled properly. You don't really have a proposal if you don't address the issue of preventing duplicate delivery. >> [Eric] Has any thought been given as to whether/how this would work >> over a VPN? > [Pierre] If the VPN transports BIER encapsulated packets, I guess it would > not be a problem. Do you have a specific concern in mind ? Are you assuming that a set of customer sites connected over an L3VPN backbone can function as a single BIER domain? The sites of a VPN usually do not participate in a common routing protocol with each other, and the BIER layer signaling is piggybacked on routing. So it's not at all obvious how to create a single BIER domain out of mulitlpe customer sites. On the other hand, if you assume that each site is an independent BIER domain, it's not obvious how listeners at one site talk to queriers at another. > [Pierre] This proposal targets implementation simplicity, at the cost of scalability.

More likely, there would have to be a sub-domain for running BMLD, and a particular flow would have to be sent in a sub-domain that contains the flow's source and all its listeners.

It is strictly a signaling protocol that allows hosts to indicated interest in a multicast group to whatever routers are listening. It seems to me that this proposal would require new work at the BIER level to control the redundant distribution of multicast data across a domain.

Agreed. There is a similar issue on the egress, where a host may be = dually connected to the BIER domain. Some sort of DR/DF election needs to b= e done in order to prevent duplication. This is a problem that is not speci= fic to this proposal. If we use BGP as the overlay (with BIER end-to-end), you run into similar problems. = This is a problem that needs to be resolved independently of the overlay IM= O.

We have idea=E2=80=99s how to resolve it, of course ;-) I=E2=80=99ll pull f= olks aside this week to discuss and plan to submit a draft on this for next= IETF.

Thx,

Ice.

This all pertains pretty much to extensions of section 6.10 Let's start with an example and then see the problems in what today's architecture document draft mandates (i.e. no signalling of conversion capability between multiple BMLs in a node, each node independently making decisions during compatibility check).

Observation a: if the bitstring compatibiilty check is disabled and normal SPF is used, this will blackhole. Even with compatibility check, Point 6.10.1 choice 1 is incorrect in the assertion that choice 2 of 6.10.2 will not blackhole (choice 3 won't but whether use choice 2 or 3 is impossible to determine in current architecture and choice 3 is basically unicast). Compatiblity check, even if using option 1. without signalling of which path computation is used may blackhole here when shortest-path is used. Observation b: using a different path computation could yield alpha,gamma,delta (blue) which does not need conversion and does not blackhole. However, the nodes have all to agree on the computation, otherwise blackholes may occur (a node fwd' towards another node may choose a path which takes the packet away from what the originating node consider shortest, observe however that BIER loop protection will cause @ most a micro-loop. In this example if gamma runs SPF it will drop packet since it wants to fwd it towards beta2 [black link] even if alpha assumes it follows the blue path based on the computation it's running). Observation c: Nodes also need to agree whether conversion is supported even if they agree on the path computation. Shortest path that does not blackhole here is beta1,beta2,beta3 (green) but if beta2 would assume doing a computation that all nodes convert, it would fwd' to gamma while gamma, since it cannot convert, would loop back @ beta2, i.e. red is the shortest path assuming e'one can convert but it's a blackhole. There are more observations but that's just a starting point to following conclusions and my comments/request on the architecture: What's my take: a) it has to be understood that the architecture with multiple BMLs may blackhole if simply SPF is used no matter what. With compatibility check the blackholing can be only avoided only if e.g. a 'BML restricted SPF' is run that includes nodes only with the packet's BML (i.e. all nodes not supporting the BML are excluded). Such a computation may blackhole even if a 'conversion path' is avaialble. b) if conversion is supported, the nodes have to signal conversion to allow for a 'smarter' path computation that can take into account this property when computing paths. In this example the shortest, converging path is alpha (A),beta1 (A),beta2 (B),beta3 (B),delta (A) (green) which is shorter than the 'BML restricted SPF' alpha(A),gamma(A),delta(A) (blue) while the simple SPF will blackhole no matter what alpha (A),beta1 (A),beta2 (B),gamma (B) (red) *So, to keep the architecture pliable to solve all those problems in the signalling/IGPs in the future (if indicated) I strongly suggest:* *A. to remove the unnecessary restriction in all places "It should be understood though that the BFIR cannot determine by signaling whether those procedures have been deployed.". **The architecture must not mandate whether such a signalling is deployed. * *B.

There are more observations but that's just a s= tarting point to following conclusions and my comments/request on the archi= tecture:=C2=A0

What's my take:
a) it= has to be understood that the architecture with multiple BMLs may blackhol= e if simply SPF is used no matter what. With compatibility check the blackh= oling can be only avoided only if e.g. a 'BML restricted SPF' is ru= n that includes nodes only with the packet's BML (i.e. all nodes not su= pporting the BML are excluded).

So, to keep the= architecture pliable to solve all those problems in the signalling/IGPs in= the future (if indicated) I strongly suggest:

without new standard work espe= cially with BGP signaling as per6513/14 and 6625. There are implementations that through a local policy can send a join only = to a single UMH. Same policy can be applied (or applies) to explicit tracki= ng which would prevent a BFER from receiving traffic from two BFIR for a gi= ven c-stream.

There are ways to solve this problem with or without new standard work= especially with BGP signaling as per6513/14 and 6625. 

There are implementations that through a local policy can send a join = only to a single UMH. Same policy can be applied (or applies) to explicit t= racking which would prevent a BFER from receiving traffic from two BFIR for= a given c-stream. That solves dual homing of a source and resulting duplication issue. 

For dual homed hosts, the issue would only apply to active-active conn= ectivity. But if you have that then host must deal with traffic duplication= anyways, so I see no point of solving this.

Proposed procedure is that instead of dropping packet it would generate signaling. This is generalizing whats done for IPv4/IPv6 packets. XX, Ericsson: BIER packet does not have any IP information. where is ICMP packet sent to: to local host, from there on it is label switched to BFIR. Ice: BFIR is in BIER packet, so should be possible to "send back" packet equally to how it's done in MPLS networks for ICMP of IPv4/IPv6 packets. Greg: not working group item yet. will consider WG adoption call. draft-chh-bier-bier-yang-00 Ran Chen 10 min --001a113cfe70ce8442051bdf15bb Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: quoted-printable

Peter from Ci= sco: BGP draft moved TLV into sub-TLV which is inconsistent
in th= e encoding scheme to the IGP BIER extensions. Please make it
cons= istent in encoding.=C2=A0

Ice: Does exactly announ= ce the properties of BIER like the IGP extensions,
networks only = running BGP will need this. Looks good. Would like to
see this ad= opted.

claificat= ion question: sam aldrin: TTL exiry - Tunnel Transport Label.
Pro= posed procedure is that instead of dropping packet it would generate
<= div>signaling. This is generalizing whats done for IPv4/IPv6 packets.
=

XX, Ericsson: BIER packet does not have any IP informat= ion.
where is ICMP packet sent to: to local host, from there on i= t is
label switched to BFIR.

Ice: BFIR i= s in BIER packet, so should be possible to "send back"
= packet equally to how it's done in MPLS networks for ICMP of IPv4/IPv6<= /div>
packets.

Greg: not working group item ye= t. will consider WG adoption call.

Wed, 29 Jul 2015 15:35:37 -0000 A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Bit Indexed Explicit Replication Working Group of the IETF. Title : Multicast using Bit Index Explicit Replication Authors : IJsbrand Wijnands Eric C. Rosen Andrew Dolganow Tony Przygienda Sam K Aldrin Filename : draft-ietf-bier-architecture-02.txt Pages : 36 Date : 2015-07-29 Abstract: This document specifies a new architecture for the forwarding of multicast data packets. It provides optimal forwarding of multicast packets through a "multicast domain". However, it does not require a protocol for explicitly building multicast distribution trees, nor does it require intermediate nodes to maintain any per-flow state. This architecture is known as "Bit Index Explicit Replication" (BIER). When a multicast data packet enters the domain, the ingress router determines the set of egress routers to which the packet needs to be sent. The ingress router then encapsulates the packet in a BIER header. The BIER header contains a bitstring in which each bit represents exactly one egress router in the domain; to forward the packet to a given set of egress routers, the bits corresponding to those routers are set in the BIER header. Elimination of the per- flow state and the explicit tree-building protocols results in a considerable simplification.

=C2=A0=C2=A0

=C2=A0 Targeted for small/averaged sised networks.

=C2=A0 Shep Q: Do you have a specific use case in mi= nd ?

=C2=A0 A: Could be applied to homenet.=

=C2=A0 A: Simple not only wrt. scale but also overal= l solution complexity.

=C2=A0

=C2=A0 BMLD queriers, BMLD Queriers

=C2=A0 Slide 6: changes required to MLD.

=C2=A0 Open issues (slide 8): prevent duplicate forw= ading.

=C2=A0 Prevent duplicated packet from leaving the ne= twork.

=C2=A0 Andrew Doglanv: Looks like extending BIER dom= ain to access side.

=C2=A0 might be better to enhance BIER itself.

Peter from Cisco: BGP draft moved TLV into sub-TLV w= hich is inconsistent

in the encoding scheme to the IGP BIER extensions. P= lease make it

claification question: sam aldrin: TTL exiry - Tunne= l Transport Label.

Proposed procedure is that instead of dropping packe= t it would generate

signaling. This is generalizing whats done for IPv4/= IPv6 packets.

=C2=A0

XX, Ericsson: BIER packet does not have any IP infor= mation.

where is ICMP packet sent to: to local host, from th= ere on it is

label switched to BFIR.

=C2=A0

Ice: BFIR is in BIER packet, so should be possible t= o "send back"

packet equally to how it's done in MPLS networks= for ICMP of IPv4/IPv6

packets.
