This draft is a work item of the Bit Indexed Explicit Replication WG of the IETF. Title : OSPFv2 Extensions for BIER Authors : Peter Psenak Nagendra Kumar IJsbrand Wijnands Andrew Dolganow Tony Przygienda Jeffrey Zhang Sam Aldrin Filename : draft-ietf-bier-ospf-bier-extensions-18.txt Pages : 11 Date : 2018-06-01 Abstract: Bit Index Explicit Replication (BIER) is an architecture that provides multicast forwarding through a "BIER domain" without requiring intermediate routers to maintain multicast related per-flow state. Neither does BIER require an explicit tree-building protocol for its operation. A multicast data packet enters a BIER domain at a "Bit-Forwarding Ingress Router" (BFIR), and leaves the BIER domain at one or more "Bit-Forwarding Egress Routers" (BFERs). The BFIR router adds a BIER header to the packet. Such header contains a bit-string in which each bit represents exactly one BFER to forward the packet to. The set of BFERs to which the multicast packet needs to be forwarded is expressed by the according set of bits set in BIER packet header. This document describes the OSPF [RFC2328] protocol extension required for BIER with MPLS encapsulation [RFC8296]. Support for other encapsulation types is outside thescope of this document. The use of multiple encapsulation types is outside the scope of this document.

Wouldn't the same box already be obligated to accept IPV4 or IPV6 multicast traffic generated locally?

Hi All,

 

There are many conflic= t scenario’s (may be a result of provisioning errors) which are not a= ddressed clearly.

Few examples and sugge= sted behaviors below.

Kindly put forth your = thoughts.

 

(1)<= /p>

BFR-A ( RouterId: A, P= refix: P1, SD0 [bfrid=3D1, bsl256[label=3Dx]] )

BFR-B ( RouterId: B, P= refix: P2, SD0 [bfrid=3D1, bsl256[label=3Dy]] )

 

Two different routers = advertising same bfr-id results in bfr-id conflict.

As per RFC 8279 sectio= n-5, BFR-A and BFR-B cannot act as BFERs and cannot receive any multicast p= acket.

 

I believe the BFR-A an= d BFR-B can continue to act as BFR’s  (Not as BFERs but just as = a BIER forwarding routers)  though it is not mentioned explicitly in t= he RFC 8279 ?

 

(2)<= /p>

BFR-A ( RouterId: A, P= refix: P1, SD0 [bfrid=3D1, bsl256[label=3Dx]] )

BFR-B ( RouterId: B, P= refix: P1, SD0 [bfrid=3D1, bsl256[label=3Dx]] )

 

Two routers advertisin= g same prefix could be a valid scenario in case of Inter-area prefix advert= isement.

However in case of int= ra-area, above could be a provisioning error.

Whether BIER should,

-  = ;        Intra-area : A= ccept. Packet is forwarded based on the prefix-source who has best path fro= m local router?

          &= nbsp;           &nbs= p; May result in packets delivered to different BFER’s just like IP r= outing.           

-  = ;        Inter-area : A= ccept. Packet is forwarded based on the prefix-source who has best path fro= m local router ?

 

(3)<= /p>

BFR-A ( RouterId: A, P= refix: P1, SD0 [bfrid=3D1, bsl256 [label=3Dx]] )

BFR-B ( RouterId: B, P= refix: P1,  SD0 [bfrid=3D2, bsl256 [label=3Dy]] )

 

Same as (2), but the b= ier parameters advertised are different.

Consider both BFR-A an= d BFR-B as non-bier capable (cannot act as BFER / BFR) ?<= /p>

Or

Resolve the conflict b= y means of some algorithm ?

-  = ;        Lesser bfr-id = wins.

-  = ;        If bfr-id is s= ame or 0, but other parameters are different ??

RFC 8279 Title: Multicast Using Bit Index Explicit Replication (BIER) Author: IJ. Wijnands, Ed., E. Rosen, Ed., A. Dolganow, T. Przygienda, S. Aldrin Status: Standards Track Stream: IETF Date: November 2017 Pages: 43 Characters: 97283 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-bier-architecture-08.txt URL: https://www.rfc-editor.org/info/rfc8279 DOI: 10.17487/RFC8279 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 bit string 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. The procedures for forwarding a packet based on its BIER header are specified in this document. Elimination of the per-flow state and the explicit tree-building protocols results in a considerable simplification. This document is a product of the Bit Indexed Explicit Replication Working Group of the IETF. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements.

HI folks,

Regarding the following text in= chap 3 of <draft-ietf-bier-mvpn>, I have a question:

   When an egress PE determines that it needs to rece= ive a (C-S,C-G)

   flow from a particular ingress PE via BIER, it originates a Leaf A-D

   route.  Construction of the Leaf A-D= route generally follows the

   procedures specified in [RFC6514], or optiona= lly, the procedures

   specified in [EXPLICIT_TRACKING].&nb= sp;

 

Is the ‘it originates a Leaf A-D route’ means that, for as few as only one SPMSI A-D= (*,*,PTA<type=3DBIER,flag=3DLIR+LIRpF>), when an egress PE first = determines to receive (C-S1,C-G1), it will only originate Leaf A-D(C-S1,C-G= 1), but not originate Leaf A-D(C-*,C-*) ?

 

The chap 3 also allows A "= less specific" x-PMSI A-D route being the egress PE's "match for = reception" of (C-S,C-G), and thus seems to imply allowing a Leaf A-D(C= -*,C-*,PTA<type=3DBIER>).

 

Also there is a text in chap 5.= 1 of <draft-ietf-bess-mvpn-expl-track-09>, which seems opposite to th= e above meaning:

       Note that= if LIR is set in the PTA of the match for reception,

       the egres= s node may need to originate one or more Leaf A-D routes

       correspon= ding to the match for tracking, as well as originating a

     &nb= sp; Leaf A-D route corresponding to the match fo= r reception.

 

Thanks

Jingrong

This draft is a work item of the Bit Indexed Explicit Replication WG of the IETF. Title : PIM Signaling Through BIER Core Authors : Hooman Bidgoli Andrew Dolganow Jayant Kotalwar Fengman Xu Mankamana Mishra Zhaohui Zhang Filename : draft-ietf-bier-pim-signaling-03.txt Pages : 13 Date : 2018-06-21 Abstract: Bit Index Explicit Replication (BIER) is an architecture that provides multicast forwarding through a "BIER domain" without requiring intermediate routers to maintain multicast related per-flow state. Neither does BIER require an explicit tree-building protocol for its operation. A multicast data packet enters a BIER domain at a "Bit-Forwarding Ingress Router" (BFIR), and leaves the BIER domain at one or more "Bit-Forwarding Egress Routers" (BFERs). The BFIR router adds a BIER header to the packet. Such header contains a bit-string in which each bit represents exactly one BFER to forward the packet to. The set of BFERs to which the multicast packet needs to be forwarded is expressed by the according set of bits switched on in BIER packet header. This document describes the procedure needed for PIM Joins and Prunes to be signaled through a BIER core. Allowing PIM routers to run traditional PIM multicast services through a BIER core.

Use a PIM signal between BFIR and BFERs need to establish neighbor relation= s before talking, so BFIR also need to send PIM Hello to BFERs also. So you can see from RFC6037 and RFC6517 that, using PIM signal between PEs = in traditional MVPN and NG-MVPN, we always need a bidirectional MI-PMSI tun= nel (or default MDT) first.=20 Also I would like to note that, there are two similar RFCs, RFC6826 and RFC= 7716, to deploy MPLS P2MP in Core network while pushing PIM aside, and have= their [Upstream PE selection] procedures. If this draft want to deploy MPLS-encapsulated BIER in Core network while p= ushing PIM aside, these two drafts can be referred, at least for the [Deter= minint EBBR on IBBR] procedure.

Title : PIM Signaling Through BIER Core Authors : Hooman Bidgoli Andrew Dolganow Jayant Kotalwar Fengman Xu Mankamana Mishra Zhaohui Zhang Filename : draft-ietf-bier-pim-signaling-03.txt Pages : 13 Date : 2018-06-21 Abstract: Bit Index Explicit Replication (BIER) is an architecture that provides multicast forwarding through a "BIER domain" without requiring intermediate routers to maintain multicast related per-flow state. Neither does BIER require an explicit tree-building protocol for its operation. A multicast data packet enters a BIER domain at a "Bit-Forwarding Ingress Router" (BFIR), and leaves the BIER domain at one or more "Bit-Forwarding Egress Routers" (BFERs). The BFIR router adds a BIER header to the packet. Such header contains a bit-string in which each bit represents exactly one BFER to forward the packet to. The set of BFERs to which the multicast packet needs to be forwarded is expressed by the according set of bits switched on in BIER packet header. This document describes the procedure needed for PIM Joins and Prunes to be signaled through a BIER core. Allowing PIM routers to run traditional PIM multicast services through a BIER core.

I noticed that the [Determining EBBR on IBBR] part is changed again and aga= in, and I do admit it is an important thing like [UMH selection] defined in= RFC6513/6514.=20 But they are different actually, because this draft mean to use a PIM signa= l between BFIR(EBBR) and BFER(IBBR), instead of a unidirectional C-Multicas= t route/Leaf AD route in RFC6513/6514. Use a PIM signal between BFIR and BFERs need to establish neighbor relation= s before talking, so BFIR also need to send PIM Hello to BFERs also. So you can see from RFC6037 and RFC6517 that, using PIM signal between PEs = in traditional MVPN and NG-MVPN, we always need a bidirectional MI-PMSI tun= nel (or default MDT) first.=20 Also I would like to note that, there are two similar RFCs, RFC6826 and RFC= 7716, to deploy MPLS P2MP in Core network while pushing PIM aside, and have= their [Upstream PE selection] procedures. If this draft want to deploy MPLS-encapsulated BIER in Core network while p= ushing PIM aside, these two drafts can be referred, at least for the [Deter= minint EBBR on IBBR] procedure.

This draft is a work item of the Bit Indexed Explicit Replication WG of the= IETF. Title : PIM Signaling Through BIER Core Authors : Hooman Bidgoli Andrew Dolganow Jayant Kotalwar Fengman Xu Mankamana Mishra Zhaohui Zhang Filename : draft-ietf-bier-pim-signaling-03.txt Pages : 13 Date : 2018-06-21 Abstract: Bit Index Explicit Replication (BIER) is an architecture that provides multicast forwarding through a "BIER domain" without requiring intermediate routers to maintain multicast related per-flow state. Neither does BIER require an explicit tree-building protocol for its operation. A multicast data packet enters a BIER domain at a "Bit-Forwarding Ingress Router" (BFIR), and leaves the BIER domain at one or more "Bit-Forwarding Egress Routers" (BFERs). The BFIR router adds a BIER header to the packet. Such header contains a bit-string in which each bit represents exactly one BFER to forward the packet to. The set of BFERs to which the multicast packet needs to be forwarded is expressed by the according set of bits switched on in BIER packet header. This document describes the procedure needed for PIM Joins and Prunes to be signaled through a BIER core. Allowing PIM routers to run traditional PIM multicast services through a BIER core.

I've reviewed the listed in the draft encapsulations and analyzed how active OAM may be identified in each of the cases. For active OAM to be more useful the test packets must be in-band with the data that is being monitored. For the GUE case, I believe, that means that an OAM test packet will have all the values that characterize the monitored flow that may affect routing the packet with exception of values of C-bit and Proto/ctype field.

Regarding OAM in GUE, the C bit can be set to indicate a control
packet which could be OAM (draft-ietf-intarea-gue-05). I imagine that
OAM could be implement in one or more ctypes. This is considered an
alternative to GUE carrying a data protocol payload, it's not
considered part of the GUE header and isn't limited by GUE header len.<= br>
The statement in Geneve description "transit devices MUST NOT attempt<= br> to interpret or process it" is true for all UDP encapsulation
protocols. The problem is that encapsulation is determined by
destination port number. As described in RFC7605, UDP port numbers
only have meaning at the endpoints, so transit devices may incorrectly
interpret packets as being an encapsulation. Incorrectly reading a
packet as encapsulation might be innocuous, but an intermediate node
modifying such a packet that it incorrectly believes is an
encapsulation would be systematic data corruption. Because of this,
probably the only robust method for in-situ OAM is Hop-by-Hop options.

This draft is a work item of the Bit Indexed Explicit Replication WG of the IETF. Title : BIER Ingress Multicast Flow Overlay using Multicast Listener Discovery Protocols Authors : Pierre Pfister IJsbrand Wijnands Stig Venaas Cui(Linda) Wang Zheng(Sandy) Zhang Markus Stenberg Filename : draft-ietf-bier-mld-01.txt Pages : 15 Date : 2018-06-29 Abstract: This document specifies the ingress part of a multicast flow overlay for BIER networks. Using existing multicast listener discovery protocols, it enables multicast membership information sharing from egress routers, acting as listeners, toward ingress routers, acting as queriers. Ingress routers keep per-egress-router state, used to construct the BIER bit mask associated with IP multicast packets entering the BIER domain.
