[radvd-devel-l] radvd multicast address

[Dustin C. Hatch]

You shouldn't have to modify the multicast address for sending RAs.
ff02::1 is defined in the RFC as the group for receiving IPv6 RAs, so
that is where client's listen for them. If you change this on your
server, you would have to change it on every client as well, in the IPv6
stack of the kernel.

If, after changing the multicast group back to the default, you still
have an issue, let us know. Also, new issues should not be sent in reply
to existing threads.
