# Enable IP multicast routing and PIM-DM on Router C in the same way Router A is configured.
(Details not shown.)
4. Display the RPF route to Source on Router B.
[RouterB] display multicast rpf-info 50.1.1.100
RPF information about source 50.1.1.100:
RPF interface: GigabitEthernet2/1/3, RPF neighbor: 30.1.1.2
Referenced route/mask: 50.1.1.0/24
Referenced route type: igp
Route selection rule: preference-preferred
Load splitting rule: disable
The output shows that the current RPF route on Router B is contributed by a unicast routing protocol
and the RPF neighbor is Router A.
5. Configure a static multicast route on Router B, specifying Router C as its RPF neighbor to Source.
[RouterB] ip rpf-route-static 50.1.1.100 24 20.1.1.2
Verifying the configuration
# Display information about the RPF route to Source on Router B.
[RouterB] display multicast rpf-info 50.1.1.100
RPF information about source 50.1.1.100:
RPF interface: GigabitEthernet2/1/2, RPF neighbor: 20.1.1.2
Referenced route/mask: 50.1.1.0/24
Referenced route type: multicast static
Route selection rule: preference-preferred
Load splitting rule: disable
The output shows the following:
• The RPF route on Router B is the configured static multicast route.
The RPF neighbor of Router B is Router C.

Network requirements
As shown in
PIM-DM runs in the network and all routers in the network support IP multicast.
•
Router B and Router C run OSPF, and have no unicast routes to Router A.
