Configuration procedure
1. Configure IP addresses and unicast routing
Configure the IP address and subnet mask for each interface as per Figure 63 . (details not shown)
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. (details not shown)
2. 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.
