Subject: [Idr] 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/<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdatatracker.ietf.org%2Fdoc%2Fdraft-chen-idr-bier-te-path%2F&data=05%7C01%7Cmichael.mcbride%40futurewei.com%7C343ad963ded249a9f35d08da5468f702%7C0fee8ff2a3b240189c753a1d5591fedc%7C1%7C1%7C637915107077512918%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C2000%7C%7C%7C&sdata=ArsO3aXzyrLrI33gIGcgaCQM4kPd0ncD4lJDVAh14AM%3D&reserved=0>).

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
