MULTICAST PROCESSING METHOD AND DEVICE

摘要

A multicast processing method, device, and system are provided. The method includes: blocking a port 1, where the port 1 is one of an egress port and an ingress port, and the other of the egress port and the ingress port is a root port; receiving a join packet from the ingress port, wherein the packet is used for a multicast user to request joining multicast; and establishing, according to multicast information of the multicast included in the join packet and port information of the ingress port, a forwarding table entry for forwarding data of the multicast from the egress port to the ingress port. Through embodiments of the present invention, an effect of shortening the multicast service recovery time is realized.
