Re: [v6ops] new draft: draft-ietf-v6ops-6204bis

I agree with Barbara: it would be better to have all the requirements related to IPv4/IPv6 migration in a single document.
When we talk about IPv6 migration we always consider also the phase of IPv4/IPv6 co-existence in order to make the transition happening. I mentioned CGN, but what I had in mind is the DS-Lite case where CGN is embedded in the AFTR and PCP fits in this scenario.

That's ok. I'm biased too. Just differently.

My bias is:
Extending the life of IPv4 and deploying IPv6 are not separate topics.
The same people are working on both, simultaneously, in order to provide
a holistic solution. While the access network may have many physical
components, and support connecting to different customers in a variety
of ways, it is engineered and designed as a whole. The vast majority of
consumer-grade customers aren't asking for IPv6 or IPv4. They want their
Internet connection to work. A single CE router must be able to provide
them with this working Internet connection. And since it all goes into
one CE router, it would be better if the CE router vendor could find it
in one document. The more places they have to look, the more likely it
is they'll miss something.

My preference is one document to describe all the stuff needed to
provide that working Internet connection.
We didn't need all the other IPv4 stuff, because we were working off an
assumption that CE router vendors already had that working, and weren't
looking for guidance.
I'd rather change the document scope than not provide guidance on new
capabilities that are critical for having a functioning Internet
connection.
