Ric, any final IETF work that involves IPv4 does has to at the very
least have detailed IPv6 considerations in order to be complete. I
understand that the DSLF IPv6 architecture for IP sessions is very
incomplete, and I am going to personally try and rectify that as much as
I can via my own participation in the Forum. This doesn't mean you are
off the hook for DHCP Auth, and I highly suggest the next version of
your document speak to this in as clear and frank a manner as possible.
Iljitsch, your comment wasn't exactly written with a constructive tone
either. Let's all please try not to push each others buttons and throw
flames here.

Doesn't seem to address IPv6. This makes it useless in my book.
Ahh, you have written a book on authentication in DSL architectures...
;-)
If you point me to the IPv6 deployment architecture from the DSLForum
I can send you a draft on how to do the authentication in it. Putting
EAP into DHCP v6 is no big trick, the real trick is what does the rest
of the IPv6 architecture look like.
There are a ton of questions like:
a) Do we have multiple services with separate addresses or are they on
the same address as IPv4. Both approaches have pro's and cons.
b) How far into the L2 architecture are link local addresses allowed.
c) SAVA
and on and on.
It is simply premature to guess at what authentication is appropriate
and while PANA seems to think they have a hammer for everything. I do
not think DHCP Authentication may be the write answer to every question.
So leave off the IPv6, we just cannot answer the question with the
architectures under discussion at the DSLForum.
