Configuration procedure
1 Configure the interface IP addresses and unicast routing protocol for each router
Configure the IP address and subnet mask for each interface as per
Detailed configuration steps are omitted here.
Configure the OSPF protocol for interoperation among the routers in the PIM-SM
domain. Ensure the network-layer interoperation among Router A, Router B,
Router C, Router D and Router E in the PIM-SM domain and enable dynamic
update of routing information among the routers 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 Router A, enable PIM-SM on each interface, and
enable IGMPv3 on Ethernet 1/0, which connects Router A to the stub network.
