Hi Jeff and Les, In general I prefer to have the 2 together (here’s the protocol details and here’s how it’s managed), IMHO there’s benefit in having the 2 together since the YANG discussions are happening while we’re in the thick of the protocol discussions. I am actually not keen to end up with 2 docs, RFC XXX and RFC YYYY: YANG for XXXX with 2 different lifecycles, by the time the YANG is done people aren’t interested anymore because the protocol spec is done. I brought this up some time ago with RTG AD and OPS AD, but I don’t think there was any conclusion.
In this specific case, I agree that there’s no protocol changes. So with 2 documents, are you proposing that the BFD spec should be informational and the YANG standards track? Or both informational? If it’s the latter, I’d rather they be in the same doc. Regards, Reshad ( no hat).

The common practice is that if the draft in question doesn’t require any protocol changes it should aim for Informational track (or BCP). https://ietf.org/standards/process/informational-vs-experimental/ I’d rather have 2 separate documents. In general, given that YANG documents life cycle is quite different from that of protocol ones, it is perhaps a good practice to keep them separate.

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

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.
