Configuration procedure
1. Assign an IP address and subnet mask to each interface according to Figure 45. (Details not
shown.)
2. Configure OSPF on the routers in the PIM-DM domain to make sure they are interoperable at the
network layer. (Details not shown.)
3. Enable IP multicast routing, PIM-DM, and IGMP:
# Enable IP multicast routing on Router A, enable PIM-DM on each interface, and enable IGMP on
GigabitEthernet 2/1/1, which connects Router A to N1.
