Currently, the Linux kernel doesn't support IPv6 multicast routing.

FYI, if you want to run IPv6 multicast routing on Linux, you would
have to patch your kernel (see
http://clarinet.u-strasbg.fr/~hoerdt/linux_ipv6_mforwarding/
and that code is already in the USAGI tree), but sadly I haven't had
the time to test XORP with that kernel patch.

If you don't need IPv6 multicast routing, then it seems you have
misconfigured your router by including "plumbing mfea6",
"protocols mld" and "protocols pimsm6". Remove those three sections
and try again.
