ABSTRACT:
The present invention provides a method and apparatus for registering to a designated router in a rendezvous point in an anycast group in a multicast communication network, wherein the rendezvous point implements a joint-registering based on registering status of all rendezvous points in the anycast group. The main rendezvous point sends to the designated router the Register Stop message only when all rendezvous points in the anycast group do not need the Register message from the designated router; when any one of other rendezvous points does not need the Register message, sending the Register message to it is stopped. With the method and apparatus of the present invention, the cases resulting in the interruption of subscriber terminal multicast traffic can be reduced, and the CPU resource of the main rendezvous point and bandwidth resources between it and other rendezvous points are saved.
