# Enable IP multicast routing and PIM-DM on Router C in the same way. (Details not shown.)
# Use the display multicast rpf-info command to view 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: Ethernet1/3, 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.
3. 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: Ethernet1/2, 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 that the RPF route on Router B has changed. It is now the configured static multicast
route, and the RPF neighbor is now Router C.
Creating an RPF route
Network requirements
As shown in Figure 41, 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. Typically, Receiver can receive
the multicast data from Source 1 in the OSPF domain.
Perform the following configuration so that Receiver can receive multicast data from Source 2, which is
outside the OSPF domain.
