information by leveraging the unicast routing protocol. The specific configuration
steps are omitted here.
2 Enable IP multicast routing, and enable PIM on each interface
# Enable IP multicast routing on Router C, enable PIM-DM on each interface, and
enable IGMPv2 on Ethernet 1/0.
<RouterC> system-view
[RouterC] multicast routing-enable
[RouterC] interface ethernet 1/0
[RouterC-Ethernet1/0] igmp enable
[RouterC-Ethernet1/0] pim dm
[RouterC-Ethernet1/0] quit
[RouterC] interface ethernet 1/1
[RouterC-Ethernet1/1] pim dm
[RouterC-Ethernet1/1] 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 1/0
[RouterA-Ethernet1/0] pim dm
[RouterA-Ethernet1/0] quit
[RouterA] interface ethernet 1/1
[RouterA-Ethernet1/1] pim dm
[RouterA-Ethernet1/1] quit
The configuration on Router B is similar to that on Router A. The specific
configuration steps are omitted here.
# Use the display multicast rpf-info command to view the information of the
RPF route to Source 2 on Router B and Router C.
[RouterB] display multicast rpf-info 50.1.1.100
[RouterC] display multicast rpf-info 50.1.1.100
No information is displayed. This means that no RPF route to Source 2 exists on
Router B and Router C.
3 Configure a multicast static route
# Configure a multicast static route on Router B, specifying Router A as its RPF
neighbor on the route to Source 2.
[RouterB] ip rpf-route-static 50.1.1.100 24 30.1.1.2
# Configure a multicast static route on Router C, specifying Router B as its RPF
neighbor on the route to Source 2.
[RouterC] ip rpf-route-static 50.1.1.100 24 20.1.1.2
4 Verify the configuration
# Use the display multicast rpf-info command to view the RPF routes to Source
2 on Router B and Router C.
