Figure 197 Network diagram for PIM-SM domain configuration
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 197.
Detailed configuration steps are omitted here.
Configure the OSPF protocol for interoperation among the switches in the PIM-SM
domain. Ensure the network-layer interoperation among Switch A, Switch B,
Switch C, Switch D and Switch E in the PIM-SM domain and enable dynamic
update of routing information among the switches through a unicast routing
protocol. Detailed configuration steps are omitted here.
2 Enable IP multicast routing, and enable PIM-SM on each interface
# Enable IP multicast routing on Switch A, enable PIM-SM on each interface, and
enable IGMPv2 on VLAN-interface 100, which connects Switch A to the stub
network.
