Configuration procedure
1. Configure the IP address and subnet mask for each interface as per Figure 50 . (Details not shown.)
2. Configure OSPF on the switches in the PIM-DM domain to ensure network-layer reachability
among them. (Details not shown.)
3. 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.
