Configuration procedure
1. Configure IP addresses for interfaces and configure OSPF (this example uses OSPF process 1)
in AS 200 to ensure intra-AS connectivity. (Details not shown.)
2. Enable IP multicast routing, PIM-SM, and IGMP, and configure BSR boundaries:
# On Switch A, enable multicast routing globally, and enable PIM-SM on interfaces.
<SwitchA> system-view
[SwitchA] multicast routing
[SwitchA-mrib] quit
[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
# Configure Switch B and Switch D in the same way that Switch A was configured.
# On Switch C, enable multicast routing globally.
<SwitchC> system-view
