Hi Brian,

 

If any of the review team reviews hasn't been done in a timely fashion, that
is not a blocker to progress. 

 

It is great that the Secdir reviewer has signed off on the update. Then we
are ready to progress with this document also. 

 

Unfortunately, I really don't want to give the IESG the documents in the
wrong order. My plan was to have BPbis and BPsec on a telechat first, then
the following have TCPCLv4. 

 

To my understanding the only real open issue to be able to progress BPbis is
the question of obsoleting 5050 and the other RG produced RFCs that are
being replaced. We are currently in a process state where we don't have a
clear decision in that question. I am working with the chairs to get that
going. 

 

Cheers

 

Magnus Westerlund

Magnus,

As of 6 December, the SECDIR reviewed the -16 draft and agreed with all of
the updates. The formal datatracker review state has not been updated yet
(as no re-review has yet been formally requested).

The GENART review has been overdue for a month now. Is there some poking
that needs to be done to progress this last review?

Thanks,

Brian S.

So my goal here was that there would be clear that there might be multiple
different versions using this particular port.

What was confusing me here and lead me down the reasoning that both should
be
listed was the expectation that BPv6 and its usage of TCPclv3 would not be
directly obsoleted, and definitely not disapear from usage. Re-reading the
IANA
section and looking at this document I think it is clear that if you
actually go
look in this docuemnt, you can figure out that TCPclv3 may also be used on
this
port. Thus, a single reference is fine with me after this additional
consideration. 

And if we are back to having BPv7 obsolete BPv6, then I think having this
direct
obosletion is fine. If we are not having the first, this document's
obsoletion
of TCPclv3 needs another thought. I note that we have not been consistent in
our
actions due to the obsoletion discussion. 

Cheers

Magnus
