draft on IPv6 multicast issues

[Pekka Savola <pekkas@netcore.fi>]

Hello all,

I've just sent a 7-page draft on IPv6 Multicast Deployment Issues to
internet-drafts@ietf.org.  In the meantime, it's available at:

http://www.netcore.fi/pekkas/ietf/draft-savola-v6ops-multicast-issues-00.txt

The abstract is:

   There are many issues concerning the deployment and implementation,
   and to a lesser degree, specification of IPv6 multicast.  This memo
   describes known problems, trying to raise awareness.  Currently,
   global IPv6 interdomain multicast is completely impossible except
   using SSM: there is no way to convey information about multicast
   sources between PIM RPs. Site-scoped multicast is also problematic
   when used alongside to global multicast because of that.  A few
   possible solutions are outlined or referred to.  In addition, an
   issue regarding link-local multicast-blocking Ethernet switches is
   brought up.  Finally, a feature request for MLD snooping switches is
   noted.

The companion document on embedding the address of the RP in the multicast
address will follow shortly.

Comments are welcome, either directly or to the list(s) if appropriate.
