{ The routers are interoperable at the network layer.
{ The routers can dynamically update their routing information.
3. Configure Router A:
# Enable IP multicast routing.
<RouterA> system-view
[RouterA] multicast routing
[RouterA-mrib] quit
# Enable PIM-SM on each interface.
[RouterA] interface ten-gigabitethernet 1/1/5
[RouterA-Ten-GigabitEthernet1/1/5] pim sm
[RouterA-Ten-GigabitEthernet1/1/5] quit
[RouterA] interface ten-gigabitethernet 1/1/6
[RouterA-Ten-GigabitEthernet1/1/6] pim sm
[RouterA-Ten-GigabitEthernet1/1/6] quit
# Configure Ten-GigabitEthernet 1/1/6 as a C-BSR and C-RP.
[RouterA] pim
[RouterA-pim] c-bsr 10.1.1.1
[RouterA-pim] c-rp 10.1.1.1
[RouterA-pim] quit
4. Configure Router B:
# Enable IP multicast routing.
<RouterB> system-view
[RouterB] multicast routing
[RouterB-mrib] quit
# Enable PIM-SM on each interface.
[RouterB] interface ten-gigabitethernet 1/1/5
[RouterB-Ten-GigabitEthernet1/1/5] pim sm
[RouterB-Ten-GigabitEthernet1/1/5] quit
[RouterB] interface ten-gigabitethernet 1/1/6
[RouterB-Ten-GigabitEthernet1/1/6] pim sm
[RouterB-Ten-GigabitEthernet1/1/6] quit
5. Configure Router C:
# Enable IP multicast routing.
<RouterC> system-view
[RouterC] multicast routing
[RouterC-mrib] quit
# Enable IGMP on Ten-GigabitEthernet 1/1/5.
[RouterC] interface ten-gigabitethernet 1/1/5
[RouterC-Ten-GigabitEthernet1/1/5] igmp enable
[RouterC-Ten-GigabitEthernet1/1/5] quit
# Enable PIM-SM on Ten-GigabitEthernet 1/1/6.
