i have strange situation here.
in my 6.3 box:
$ asmping ff38:20:2001:d30::
asmping joined (S,G) = (*,ff38:20:2001:d30::4321:1234)
pinging 2001:d30:111:2::4 from 2001:d30:101:1::10

  rtt min/avg/max/std-dev = 334.344/341.109/347.627/5.446 ms

in my 7.1 box:
$ asmping ff38:20:2001:d30::
Failed to join multicast group: Protocol not available

both boxes has same ipv4 subnet and same ipv6 link.
7.1 box has options MROUTING
6.3 box does not has options MROUTING

do i miss something here?

best regards,
