Abstract:
1. A method for processing a multicast packet, the method comprising: combining multicast routing entries having a same clustered routing system interface, allocating a corresponding internal shared tree identity, and saving mapping between a multicast routing entry and the internal shared tree identity; establishing mapping between the internal shared tree identity and a local router interface in a clustered routing system according to the mapping between the multicast routing entry and the internal shared tree identity, mapping between the multicast routing entry and the clustered routing system interface, and mapping between the clustered routing system interface and the local router interface in the clustered routing system, and saving the mapping between the internal shared tree identity and the local router interface in an internal multicast forwarding information base of each local router; receiving a multicast packet; acquiring the local router interface corresponding to the multicast packet according to the multicast routing entry carried in the multicast packet; and forwarding the multicast packet through the acquired local router interface to the clustered routing system interface for further transfer.
