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 4-7

. Detailed configuration

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.
