The chairs have received a request from the authors of

http://tools.ietf.org/html/draft-fan-idr-ipv6-bgp-id
  "IPv6 BGP Identifier Capability for BGP-4", Peng Fan, Zhenqiang Li,
  2014-02-12

who would like to discuss it with other operators in the coming meeting. It is, of course, an idr draft and will be pursued there. But idr thinks it has a solution for this problem in 

https://tools.ietf.org/html/rfc6286
6286 Autonomous-System-Wide Unique BGP Identifier for BGP-4. E. Chen,
     J. Yuan. June 2011. (Format: TXT=7497 bytes) (Updates RFC4271)
     (Status: PROPOSED STANDARD)

which relaxes the definition of the BGP Identifier to be a 4-octet, unsigned, non-zero integer and relaxes the "uniqueness" requirement so that only Autonomous-System-wide (AS-wide) uniqueness of the BGP Identifiers is required. In other words, in an IPv6-only AS, the operator may assign a 32 bit value as his BGP Identifier. China Mobile finds this cumbersome, requiring what amounts to planning and manual intervention in something that is automatic in IPv4 networks, and would like to be able to use an IPv6 address as a BGP identifier directly.

The question, post-discussion, is whether v6ops should advise idr that the draft would be of operational interest and value.

Do you want John and I to include it in the agenda?
