[0040] In order to solve the problems existing in the prior art, the multicast packet forwarding method and communication equipment adopted in the present invention are to determine that the interface that the multicast packet arrives at is determined by the communication equipment according to the ACL issued for each interface. When the multicast message should reach the interface, modify the VLAN information or VPN information of the received multicast message to the reserved VLAN information or VPN information of the RP where the interface is located, and search and modify through the created multicast forwarding table The outbound interface corresponding to the multicast packet following the VLAN information or VPN information is forwarded. Therefore, the method of the present invention can not only realize the forwarding of multicast messages in bidirectional PIM, but also the communication equipment does not need to create multicast table items according to the number of ...
