I got one comment to our draft. Section 5.4 discusses some known neighbor
discovery issues out there. I forgot to add one that I believe belongs here or
then in Section 5.2; which one I am not sure yet. In Section 5.2 it is said
that the GGSN/PGW provides an unique IID to the UE (i.e. guaranteed not to
collide with GGSN/PGW's one) for the link-local address configuration. However,
numerous modem drivers today fail (or don't even care) to deliver the received
IID to the host OS stack and instead the driver comes up with its own (usually
some imaginary MAC address based one..). Therefore, there is theoretical but
very unlikely chance for link-local address collision between the UE and the
gateway on the 3GPP link. Since the UE may or may not perform DAD this can be
unnoticed during the address configuration phase.

2011/8/2, The IESG <iesg-secretary(_at_)ietf(_dot_)org>:
The IESG has received a request from the IPv6 Operations WG (v6ops) to
consider the following document:
- 'IPv6 in 3GPP Evolved Packet System'
<draft-ietf-v6ops-3gpp-eps-03.txt> as an Informational RFC
The IESG plans to make a decision in the next few weeks, and solicits
final comments on this action. Please send substantive comments to the
ietf(_at_)ietf(_dot_)org mailing lists by 2011-08-15. Exceptionally, comments
may be
sent to iesg(_at_)ietf(_dot_)org instead. In either case, please retain the
beginning of the Subject line to allow automated sorting.
Abstract
Use of data services in smart phones and broadband services via HSPA
and HSPA+, in particular Internet services, has increased rapidly and
operators that have deployed networks based on 3GPP network
architectures are facing IPv4 address shortages at the Internet
registries and are feeling a pressure to migrate to IPv6. This
document describes the support for IPv6 in 3GPP network
architectures.
