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

[Jørgen Hovland]

You didnt give much information like if you are using dvmrp tunnels etc..
Your cisco is in front of the linuxmachine on a seperate interface which does the tunneling? 
LAN1 <-> cisco <-> linux LAN2 <-> tunnel <-> linux <-> LAN3 ?
Are all the nodes in the same domain ? How is your pim configuration set?

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

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.
