Happy to see this draft moving along and also publication of 5569,
especially in the light of Comcast announcement of an end-user trial of
IPv6 including 6rd.
I have read the draft and agree it is ready for WGLC, with a couple
nits/questions
1. Intro: Spell out the term Border Relay (BR) router on first use in
intro; it is a new term being introduced here.
6. Address Selection: is the statement meant to be normative SHOULD for
6rd implementation, or is it just a hopeful observation (about other
nodes behavior)? I.e. one can expect 6rd delegated prefixes to be
treated as native IPv6 addresses in address selection.
7.1.1. 6rdPrefixLength: why does DHCP bounds checking to allow 128 bits
when the 6rd delegated prefix MUST be /64 or less?
8. Neighbor Unreachability Detection: the statement about NUD could be
stronger than "not recommended", especially since later it is stated
that the CE MUST utilize a method which does not require special
processing. Also, the mechanism seems reasonable and flexible enough to
be the required method rather than just "one such method."

Softwires,
Happy New Year all. I hope none of you are fixing Jan 1, 2010 bugs in
your code these days ;-)
You may have seen a -02 followed quickly by a -03
draft-ietf-softwire-ipv6-6rd. The reason for the quick rev was a math
bug in one of the recommended bounds checks that we let get into -02.
Thanks to Jerry Huang for bringing it to our attention. We thought it
was important enough to be fixed right away, as we hope this it the
version that we can take to last call, and understand that
implementations may be in the works as well.
-03 includes quite a bit of text cleanup, and addresses comments
received in Hiroshima, on-list, and some side comments that came in as
well.
Chairs,
Apologies for not meeting the "one week after Hiroshima" or even our
own self-imposed "before the Holidays" deadline. On the bright side,
we made it in before the pre-Anaheim deadline rush! Everyone should
have plenty of cycles to review for us right now. So, unless there is
any major objection, I'd like to request a Last Call.
Many Thanks,
- Mark
