IPv6 multicast groups (ff02::1, ff02::2)

Also written: ff02::1, ff02::2, all nodes, all routers, 33:33:00:00:00:01, 33:33:00:00:00:02

Two fixed IPv6 multicast groups on the local link: ff02::1 reaches all nodes, and router advertisements go there, while ff02::2 reaches all routers, and router solicitations go there.
