[6bone] Call for help: Multicast over tunneled ipv6

[Kimmo Suominen]

I was just looking at this the other day, and I didn't see a "ipv6
multicast-routing" command (analogous to "ip multicast-routing")
on IOS 12.2(11)T.  Which made me think it doesn't do multicast over
ipv6 at all.

Regards,
+ Kim

| Has anyone had any luck using multicast over a tunneled v6 connection?
| Everything works on the local ethernet segment (of course), but I can't
| get past the router--the other end doesn't see any of the multicast
| packets.  (I was testing with an ipv6ip tunnel to another site in this
| case)
|
| It's quite possible that I don't have the router set up correctly, but I
| don't know what I'm doing wrong if that's the case.  I've been browing
| assorted multicast docs on cisco's site, and *as far as I know*, I have
| everything configured correctly.
|
| Can anyone suggest any possible 'gotchas' or condensed guides?
|
| Some details:
| Router: Cisco IOS Version 12.2(8)T5
| Nodes on each end: Linux 2.4.x (16 <= x <= 19)
|
| IPv6 on the local ethernet segment is native until the router
| Router connects to the world with 6to4
| Test nodes were connected by means of native ipv6 -> router -> ipv6ip
| over v4 internet -> ipv6 sit interface in Linux
|
| I'd be happy to provide configuration snippets or other details if
| they'll help.
