Configuration procedure
1. Assign an IP address and subnet mask to each interface according to Figure 45. (Details not
shown.)
2. Configure OSPF on all routers on the PIM-SM network to make sure the following conditions are
met: (Details not shown.)
{ The routers are interoperable at the network layer.
{ The routers can dynamically update their routing information.
3. Enable IP multicast routing, IGMP, and PIM-SM:
# On Router A, enable IP multicast routing.
<RouterA> system-view
[RouterA] multicast routing
[RouterA-mrib] quit
# Enable IGMP on GigabitEthernet 2/1/1 (the interface that connects to the receiver host).
[RouterA] interface gigabitethernet 2/1/1
