I know the latest xorp.ct and kernel 2.6.34+ can work with IPv6 multicast, but there may still be issues
we haven't found, and I don't think we've tested your scenario.

If you do fix it, please post a patch and I'll try to integrate it into xorp.ct.

Or, it may be a kernel bug, in which case you might try 2.6.36 kernel
and hope someone has fixed it (I'd be interested to see any kernel patch you
might come up with as well..)

Thanks,
Ben
