Only the commands related to multicast static route configuration are listed in the
configuration procedure.
1 Configure the interface IP addresses and unicast routing protocol for each switch
Configure the IP address and subnet mask for each interface as per Figure 164.
The detailed configuration steps are omitted here.
Enable OSPF on Switch A, Switch B and Switch C. Ensure the network-layer
interoperation among the switches. Ensure that the switches can dynamically
update their routing information by leveraging the unicast routing protocol. The
specific configuration steps are omitted here.
2 Enable IP multicast routing, and enable PIM on each interface
# Enable IP multicast routing on Switch C, and enable PIM-DM on each interface.
