Configuration procedure
1. Configure IP addresses and unicast routing.
Configure the IP address and subnet mask for each interface as per Figure 53 . (Details not shown)
Configure OSPF on the switches in the PIM-DM domain to ensure network-layer reachability among them.
(Details not shown)
2. Enable IP multicast routing, and enable PIM-DM and IGMP.
# 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.
