Configuration procedure
1. Configure IP addresses for interfaces. (Details not shown.)
2. Configure OSPF. (Details not shown.)
3. Enable IP multicast routing, PIM-SM and IGMP, and configure a PIM-SM domain border:
# Enable IP multicast routing on Switch A, and enable PIM-SM on each interface.
<SwitchA> system-view
[SwitchA] multicast routing-enable
[SwitchA] interface vlan-interface 100
[SwitchA-Vlan-interface100] pim sm
[SwitchA-Vlan-interface100] quit
[SwitchA] interface vlan-interface 101
[SwitchA-Vlan-interface101] pim sm
[SwitchA-Vlan-interface101] quit
The configuration on Switch B and Switch D is similar to the configuration on Switch A.
