Hi!

I just posted -15...

I looked at this new update.  Just a couple of comments:

C1. S5.1 sounds very hand-wavy: “...guiding principle for the implementor
should be that if there is no realistic hope that forwarding can
continue…”.   I’m not a programmer, but I have no idea how hope can be
coded in…  I think that unless someone has a significant objection later on
(IETF LC, IESG), we can leave the text as is, given that it is correctly
qualified as suggestions… I don’t have a suggestion to make the text
better, it may be the best we can do…it just doesn’t give me a warm fuzzy
feeling…

C2. Even though S5.2. (Interaction With Other Specifications) qualifies
that it applies to “when [RFC8203] is used in conjunction with Hard Reset”,
I think that is the general case (not the exception), so I think that this
document Updates rfc8203 (and should be tagged as such).  Please make that
change on the next revision (you can wait to collect IETF LC comments).

I’m starting the IETF Last Call.

Thanks!

Alvaro.
