Since myself - and others still believe the consensus call was fundamentally flawed and a violation of process - we actually welcome this continuing so that we can finally officially lodge the prepared appeals.  Thank you for this

Subject: Re: [spring] WGLC - draft-ietf-spring-srv6-network-programming


it's been more than a month since the e-mail below.
In the meantime there were few updates. These updates cover the
resolution of Brian's (v11 and finally v12) and Joel's (v13 and finally
v15) concerns, plus some other minor changes.

Also, there were other comments:
- on the relation with 4291. This comment had already been made at the
time of WG adoption and responded to at that time.
- on how much address space is needed to operate SRv6. The conclusion
here was about not adding recommendations in this document. However, I
encourage people with the interest and knowledge to continue the
discussion and identify whether something needs to be documented somewhere.
- on the conditions in which the upper-layer header is processed. This
lead to no change in the document.

These changes bring valuable clarifications but do not affect the
functional specification. I think we can now move forward.

I very much understand that dissatisfaction persists in relation to the
"8200 discussion". This will be reflected in the shepherd report, such
that, ultimately, the IESG is made aware.

Bruno is the shepherd.
