Configuration procedure
1. Assign IP addresses and configure unicast routing:
a. Assign an IP address and subnet mask to each interface according to Figure 41. (Details not
shown.)
b. Enable OSPF on Router B and Router C to make sure they are interoperable at the network
layer and they can dynamically update their routing information. (Details not shown.)
2. Enable IP multicast routing, and enable PIM-DM and IGMP:
# Enable IP multicast routing on Router C, enable PIM-DM on each interface, and enable IGMP on
Ethernet 1/1.
<RouterC> system-view
[RouterC] multicast routing-enable
[RouterC] interface ethernet 1/1
[RouterC-Ethernet1/1] igmp enable
[RouterC-Ethernet1/1] pim dm
[RouterC-Ethernet1/1] quit
[RouterC] interface ethernet 1/2
[RouterC-Ethernet1/2] pim dm
[RouterC-Ethernet1/2] quit
# Enable IP multicast routing on Router A and enable PIM-DM on each interface.
<RouterA> system-view
[RouterA] multicast routing-enable
[RouterA] interface ethernet 1/1
[RouterA-Ethernet1/1] pim dm
[RouterA-Ethernet1/1] quit
[RouterA] interface ethernet 1/2
[RouterA-Ethernet1/2] pim dm
[RouterA-Ethernet1/2] quit
# Enable IP multicast routing and PIM-DM on Router B in the same way. (Details not shown.)
# Use the display multicast rpf-info command to view the information of the RPF route to Source 2
on Router B and Router C.
