Irritation is irrelevant. What's relevant is that the IETF is a slow
moving standards organization. Unless a lot of people are very wrong,
any work started today will be relevant during the period in time
where we run out of IPv4 addresses. The way I see it, that makes it
necessary for any and all technologies that the IETF works on, and
especially the ones that it starts new work on, must be able to work
with both IPv4 and IPv6. Maybe the IPv6 part isn't going to be
implemented immediately. That's a decision that each vendor / service
provider has to make for themselves. But the IETF can't ignore IPv6,
which, so far, pretty much all participants in this discussion have
been doing.
This would not be the first proposal to enter the IETF with its primary
focus on IPv4. Indeed, during my tenure on the IESG I have reviewed a
number of documents which either did not have IPv6 basics included at
all, or did in passing with a number of associated errors and omissions.
It is for this that I asked Margaret Wasserman to give a tutorial
presentation at the int-area meeting a year or so ago to identify common
problems that she had seen with documents which do not correctly
consider IPv6. I think she did a great job.
So, while you certainly are solving problems with IPv6 in the forefront
of your mind, not all of the IETF, or industry at large, is. It is
clearly our job as shepherds of IPv6 to make sure that anything
developed for IPv4 works with IPv6, and as well to design new and
improved capabilities into IPv6 that do not exist in IPv4. However, to
suggest that new work on IPv4 be halted because the authors did not
start out with IPv6 in the forefront of their minds is rather unrealistic.
Back to the issue at hand, I see no technical reason why EAP in DHCPv6
would not work in largely the same fashion as the proposed EAP in
DHCPv4. I doubt the authors have any aversion at all to specifying this
in detail, with the help of the IETF to ensure that it is done correctly.
As for IPv6 deployment for DSL, I will be raising this at the
architecture group session and plenary during the next quarterly DSL
Forum meeting in the hopes of spurring more active development and
deployment.
