Configuration procedure
1. Assign an IP address and subnet mask to each interface according to Figure 47. (Details not
shown.)
2. Configure OSPF on all switches on the PIM-SM network to meet the following requirements:
(Details not shown.)
{ The switches are interoperable at the network layer.
{ The switches can dynamically update their routing information.
3. Enable IP multicast routing, and enable IGMP and PIM-SM:
# On Switch A, enable IP multicast routing.
<SwitchA> system-view
[SwitchA] multicast routing
[SwitchA-mrib] quit
# Enable IGMP on VLAN-interface 100 (the interface that connects to the receiver host).
[SwitchA] interface vlan-interface 100
[SwitchA-Vlan-interface100] igmp enable
[SwitchA-Vlan-interface100] quit
