RE: Working Group Last Call for draft-ietf-bfd-unsolicited (ending 16 August, 2020)

["Les Ginsberg (ginsberg)" <[e-mail]>]

So, I won’t prolong what is now becoming an administrative discussion – except to say:

If the standards part of the document is the YANG model, then the draft should be renamed to indicate that it is a YANG document – and the description of the implementation behavior (Section 2 mostly) is just there as supportive context.
Otherwise, we have a case of the tail wagging the dog…

But, I leave it to others to decide what to do.

For me, the most important thing is that the content is good.
It might be good to have a statement in the draft that specifies no protocol changes are introduced – which I gather will be discussed as part of reviewing Greg’s comments.

Indeed, draft-chen-bfd-unsolicited was informational and with the addition of the YANG module draft-ietf-bfd-unsolicted was changed to standards track.

Hi Les,

While shifting to Informational would be perhaps ok protocol wise - isn't it common practice in IETF that any draft (or at least most of them) which define a YANG model is a Standards Track document ?

I hope you are not suggesting to split this one into two :).

Thx,
R.

Sorry to be tardy in responding...

As I stated almost 2 years ago when this draft was introduced:

a)The problem the draft is addressing is real and the solution useful

b)There are implementations which have already addressed this problem with no interoperability issues

c)I do not see that any changes have been made to the BFD protocol (e.g. RFC 5881)

Therefore, I think this should go forward - but as Informational.
