RE: A question on OAM section in draft-ietf-opsawg-l3sm-l3nm

[[e-mail]]

Hi Greg,

FWIW, the agreed changes are now implemented in the module. You can track them at:
https://github.com/IETF-OPSAWG-WG/lxnm/commit/9b97016743a355f2b7737288dfaedebcdc47c9b8

Also, made the companion changes to the I-D: https://tinyurl.com/l3nm-latest

Cheers,
Med

Hi Med,
thank you for your thoughtful consideration of my late comments.

Regards,
Greg

Re-,

The IETF LC was actually closed since 2021-08-06.

Even if the IETF LC is closed, the current BFD comments will be part of the comments we will be addressing in the next iteration. For your record, we have already recorded the name alignment fix, the missing default clause, holdtime explanation, and session type indication.

If there are any other comments, please let us know.

Thank you.

Cheers,
Med
