Abstract
Examples of a SPB based multicast forwarding method are disclosed. Bridges in a SPBM network perform a multicast monitoring process, learn about multicast router and members of the IP multicast group, and notify other bridges in the SPBM network of the information through a SPB-ISIS LSP. A SPBM bridge in the SPBM network receives and parses the SPB-ISIS LSP, and configures the ingress and egress of the bridge, so as to guide the forwarding of IP multicast packets.
