Abstract
A method and device for registering a multicast source and establishing a multicast path are disclosed. The method includes: after receiving a multicast message of a multicast source, a designated router DR to which the multicast source belongs encapsulating a multicast header for the multicast message, wherein a target address of the multicast header is a multicast address, and a source address of the multicast header is a proxy care-of address of the multicast source; and after encapsulating the multicast header for the multicast message, encapsulating the multicast message as a registration message to send to a rendezvous point. In the embodiments of the present document, with the proxy care-of address of the multicast source in a PMIPv6 domain, and by the provided method for establishing the multicast path, the multicast routing efficiency and the multicast performance can be improved.
