Configuration procedure
1. Configure IP addresses and unicast routing
Configure the IP address and subnet mask for each interface as per Figure 62 . (details not shown)
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. (details not shown)
2. Enable IP multicast routing, enable PIM-SM on each interface, and configure a PIM-SM domain
