Pv6 Multicast Addresses

IPv6 retains the use and function of multicast addresses as a major address class. IPv6 prefix FF00::/8 is allocated for all IPv6 multicast addresses. IPv6 multicast addresses are described in RFC 2373. EIGRP for IPv6, OSPFv3, and RIPng routing protocols use multicast addresses to communicate between router neighbors.

The format of the IPv6 multicast address is described in Chapter 8, "Internet Protocol Version 6." The common multicast addresses are repeated in Table 12-3.
