Bess WG:

IDR has begun an adoption call for draft-chen-idr-bier-te-path-04.txt.
since this document specifies BGP mechanisms
(an NLRI and additions to the BGP TEA), the adoption call
Is going on in IDR.

We welcome your comments on this draft on the IDR thread:
(click below to go directly to the mail thread online)
https://mailarchive.ietf.org/arch/msg/idr/tKgu_S5_32_l5YzWfO8481hpRRY/

The IDR Chairs would appreciate feedback on
how this interacts with existing multicast VPNs specifications
existing (specified in the bess WG  or other WGs).

Another avenue of input is to provide feedback directly to the
bess chairs.   The IDR Chairs will be checking with the bess chairs
prior to finalizing the adoption of this attribute.

Cheers,
Sue Hares
(IDR co-chair, document shepherd)

Subject: WG adoption call for draft-chen-idr-bier-te-path-04.txt (6/22/2022 to 7/6/2022

This begins a 2 week Adoption call (6/22/2022 to 7/6/2022)
for draft-chen-idr-bier-te-path-04.txt
(https://datatracker.ietf.org/doc/draft-chen-idr-bier-te-path/).

This draft provides extensions to BGP to distribute BIER
(bit replication traffic/tree) data via BGP using a
new NLRI (AFI = IPv4 or IPv6, new SAFI) and
new options for the Tunnel Encapsulation Attribute (TEA).
The NLRI includes an RD + Bier Domain tunnel identifier.

In your comments, please consider if this draft:

1) Does this draft specify appropriate BGP mechanisms for
a controller to distribute bier information?

2) Does this mechanism correctly integrates into
a) the BIER architecture (draft-ietf-bier-te-arch) and
b) Multicast VPNs (BESS)?

3) Will this technology aid the deployment of
Bier multicast forwarding in operational networks?

Cheers, Sue
