Embodiment Construction
[0062] The core idea of the present invention is: through the combination of S and G, namely (S, G) mapping DMAC obtains SS-DMAC (Source-special DMAC, source-specific DMAC), Ethernet switching equipment configures forwarding port list based on SS-DMAC, router When performing Ethernet encapsulation of SSM-related IP messages, the SS-DMAC address is encapsulated into the message as a DMAC address, so that the DMAC address contains the information of the multicast source SIP, so that the Ethernet switching device performs VLAN+ based SSM can be supported during multicast forwarding of DMAC.
[0063] The specific process is:
[0064] Firstly, the corresponding relationship between (S, G) of the SSM and the DMAC is established in the router. When the router performs Ethernet encapsulation of the SSM multicast IP message, it does not use the AS-DMAC obtained only based on the multicast IP address, but obtains the SS-DMAC according to the correspondence between (S, G) and the DMAC...
