Hi Ashesh,
as in RFC 7130, each BFD session on an interface is independent. The BFD state
change may be available to LACP and/or LAG manager in the node. LAG state
coordination is outside of scope but I speculate that one can use ICCP.
Regards,
Greg

Authors,
Quick note on both drafts. They do not indicate how the BFD state is
coordinated across the MC-LAG.
-- Node B
Node A |
-- Node C
If one member link between A and B fails, how is the info propagated to BFD on
node C?
Does the system rely on LACP?
Regards,
Ashesh

Hi Jeff,
we have not expected this question that early :)
Yes, there's IPR associated with these drafts that would be properly disclosed
after the meeting.

Working Group,
These documents reasonably extend the existing BFD on LAG mechanism and would
be reasonably in charter for BFD to pick up.
Greg, given that adoption seems a reasonable course, could you and the other
co-authors state whether there's any known IPR on these documents?
