ABSTRACT:
A multicast method includes joining a multicast group and forwarding a multicast data packet; during joining the multicast group, establishing multicast forwarding instruction information identified by a MFEC, on a network node of a distribution tree or a distribution sub-tree to which the MFEC pertains; and during forwarding the multicast data packet, forwarding multicast data packets of the same MFEC, according to the multicast forwarding instruction information. The invention further discloses a multicast method, including: classifying a collection of multicast data packets forwarded in the same mode into a MFEC; statically configuring multicast forwarding instruction information identified by the MFEC on a network node of a distribution tree or a distribution sub-tree to which the MFEC pertains; and forwarding the multicast data packets of the same MFEC, according to the multicast forwarding instruction information. The invention further discloses a multicast routing method.
