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
steps are omitted here.
Configure the OSPF protocol for interoperation among the switches in the PIM-DM domain. Ensure the
network-layer interoperation among Switch A, Switch B, Switch C and Switch D in the PIM-DM 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-DM on each interface
# Enable IP multicast routing on Switch A, enable PIM-DM on each interface, and enable IGMP on
VLAN-interface 100, which connects Switch A to the stub network.
