It is required that Switch C and Switch E be configured as static RPF peers of Switch B, and
Switch B be configured as the only static RPF peer of Switch C and Switch E, so that any switch
can receive SA messages only from its static RPF peer(s) and permitted by the corresponding
filtering policy.

Configuration procedure
1) Configure IP addresses and unicast routing
Configure the IP address and subnet mask for each interface as per
Detailed configuration
steps are omitted here.
Configure OSPF for interconnection between the switches. Ensure the network-layer interoperation in
each AS, and ensure the dynamic update of routing information among the switches through a unicast
routing protocol. Detailed configuration steps are omitted here.
2) Enable IP multicast routing, enable PIM-SM and IGMP, and configure a PIM-SM domain border
# Enable IP multicast routing on Switch A, enable PIM-SM on each interface, and enable IGMP on the
host-side interface VLAN-interface 200.
