Yes, all MLD messages must include the IPv6 Router Alert option.
I just tested it on FreeBSD-7.0, and the Query messages actually
include the Router Alert extension header, so the problem is
probably OS-specific.
If this option is missing in your setup, then this is a bug. In that
case please submit a Bugzilla entry with information how to
reproduce the problem, OS version, etc.
