Only the commands related to the PIM-DM configuration are listed below.
1 Configure the interface IP addresses and unicast routing protocol for each
switch
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.
Configure the IP address and subnet mask for each interface as per Figure 183.
Detailed configuration steps are omitted here.
