# Configure Router C in the same way as you configure Router A. (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: GigabitEthernet2/0/3, 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.

4. 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

5. Verify 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: GigabitEthernet2/0/2, 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

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.
