[AG-TECH] AG IPv6 support

FYI, MLDv2 support is in the next version of Windows, Longhorn.  If
there are folks who want to give this a try, I can see about arranging a
copy of the preview release of Longhorn that was distributed at our
Professional Developers Conference this fall which has MLDv2 support in
it.

The TCP/IP implementation in Microsoft Windows code named Longhorn
("Longhorn") will include many enhancements over our Windows XP and
Windows Server 2003 stacks. 

We are currently planning to include support for MLDv2 and developers
who received early, pre-release copies of Longhorn at the Professional
Developers Conference are strongly encouraged to try out our current
implementation and send us feedback.

Any comments on this thread discussing IPv6 Multicast & Windows
limitations?

I agree there will be no MSDP for IPv6.  In 6NET we have proposed the
embedded RP method of inter-domain Any Source Multicast, as per:
http://www.ietf.org/internet-drafts/draft-ietf-mboned-embeddedrp-01.txt

This has been implemented by Cisco and validated in the 6NET network.

MLDv2 implementations do exist, particularly for BSD; its Windows that's
lacking I agree.

I believe this has been run in 6NET (www.6net.org) with native IPv6 and
the m6bone (www.m6bone.net) which is mainly tunnelled.

OK, I don't know the Abilene status; the Juniper IPv6 multicast
implementation status may well be different to Cisco.

I guess the European activity in Multicast IPv6 hasn't been disseminated
widely enough in the US?
