According to the RPF principle, the device can receive SA messages that pass the filtering policy from its static RPF peers. To share multicast source information among PIM-SM domains without changing the unicast topology structure, configure MSDP peering relationship for the RPs of the PIM-SM domains and configure static RPF peering relationship for the MSDP peers to share multicast source information among the PIM-SM domains.

Configure the IP address and subnet mask for each interface as per Figure 55. (Details not shown.) 2. Configure OSPF on the switches in each AS to make sure the switches in each AS are interoperable at the network-layer, and they can dynamically update their routing information. (Details not shown.) 3. Enable IP multicast routing, enable PIM-SM and IGMP, and configure a PIM-SM domain border: # Enable IP multicast routing on Switch C, enable PIM-SM on each interface, and enable IGMP on the host-side interface VLAN-interface 200. system-view 173
