ABSTRACT:
In a communications network, a home domain of the network formulates a multicast packet destined to a first multicast address locally unique in the home domain, encapsulates the packet in a packet destined to a second multicast address other than an individual care-of address, and transmits the packet. A mobile node visiting a foreign domain receives a packet containing the second multicast address. In a foreign-to-home multicast transmission, the visiting mobile node formulates a multicast packet destined to the first multicast address, encapsulates the packet in a packet destined to the second multicast address and transmits the packet. In the home domain, a packet containing the second multicast address is received and decapsulated to extract a packet destined to the first multicast address. The second multicast address is either a globally unique multicast address or a foreign local multicast address which is locally unique in the foreign domain.
