While I think there is pretty strong support for this draft in the WG, I do
not believe that the Routing Directorate review comments that were sent 3
January 2018 have been resolved. In particular those related to OAM which
were also discussed on the BABEL WG mailing list. I believe that if we just
declare consensus in the WG and request publication of the current draft,
our AD or the IESG will just bounce the document back to us for the reason
given in the Routing Directorate review. (There is also an Operations
Directorate review pending which I think will say the same thing when it is
done.) The BABEL WG Charter says "Particular emphasis will be placed on
work needed for a Proposed Standard routing protocol, such as ensuring
manageability and strong security. "

OK, I'll start the WG Last Call. I believe this draft should be normatively
dependent on rfc6216bis.

"Adopting" isn't that big a deal. People can review and discuss this draft
on the BABEL WG mailing list prior to adoption. So I don't see any rush.
I'll consider this message by Juliusz to be the start of a 2-week adoption
call.

As I said in London, I think it would be fairly easy to get a 2nd port
assigned if we want.

I think you need at least authentication for Hello/IHU.

Sounds like a reasonable course of action.

Sounds good. Of course, anyone is welcome to review it.


6. Applicability document. The BABEL WG Charter says:

- As the Proposed Standard version of Babel is completed, an
Applicability Statement should be finalized to guide those potentially
interested in deploying Babel. This Applicability Statement may
include deployment advice and will be published as an RFC.


Given that there clearly are applicability criterion (there are occasional
posts to the mailing list that some particular application is or is not
appropriate for BABEL) and that I think the effort to produce an acceptable
applicability draft is pretty small, it a bad sign that
draft-ietf-babel-applicability-01.txt has been expired for over 6 months.

Thanks,
Donald
