Configuration procedure
1. Configure IP addresses for interfaces and configure OSPF for each AS to ensure intra-AS
connectivity. (Details not shown.)
2. Enable IP multicast routing, PIM-SM, and IGMP, and configure BSR boundaries:
# On Router A, enable multicast routing globally, and enable PIM-SM on interfaces.
<RouterA> system-view
[RouterA] multicast routing
[RouterA-mrib] quit
[RouterA] interface gigabitethernet 2/1/1
[RouterA-GigabitEthernet2/1/1] pim sm
[RouterA-GigabitEthernet2/1/1] quit
[RouterA] interface pos 2/1/0
[RouterA-Pos2/1/0] pim sm
[RouterA-Pos2/1/0] quit
# Configure Router B and Router D in the same way that Router A was configured.
