z It is required that the respective Loopback 0 of Switch B, Switch C and Switch E be configured as
the C-BSR and C-RP of the respective PIM-SM domains.
z It is required that an MSDP peering relationship be set up between Switch B and Switch C
through EBGP, and between Switch C and Switch E through IBGP.

Configuration procedure
1) Configure IP addresses and unicast routing
Configure the IP address and subnet mask for each interface as per Figure 7-5 . Detailed configuration
steps are omitted here.
Configure OSPF for interconnection between switches in each AS. Ensure the network-layer
interoperation among each AS, and ensure the dynamic update of routing information between the
switches through a unicast routing protocol. Detailed configuration steps are omitted here.
2) Enable IP multicast routing, enable PIM-SM on each interface, 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.
