Hi!

After reading the messages in this thread, I’m returning the document to the WG to finish the discussion there.

Based on the discussion, I think there are some open items that I would like the WG to close on (in no particular order):

- Should this document address all messages or just UPDATES?  [The Chairs asked for feedback from grow.]

- Are any updates needed to the FSM?

- Is it ok to send/accept Extended Messages without having received/advertised the Capability?  This is a significant change in the way BGP operates – and would set an important precedent.

- What about incremental deployment?  Should there be operational guidance?  If so, what should that guidance be?


Thanks!

Alvaro.
