# Enable IP multicast routing and PIM-DM on Switch C in the same way Switch A is configured.
(Details not shown.)
4. Display RPF information for Source on Switch B.
[SwitchB] display multicast rpf-info 50.1.1.100
RPF information about source 50.1.1.100:
RPF interface: Vlan-interface102, 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 Switch B is contributed by a unicast routing
protocol and the RPF neighbor is Switch A.
5. Configure a static multicast route on Switch B and specify Switch C as its RPF neighbor on the
route to Source.
[SwitchB] ip rpf-route-static 50.1.1.100 24 20.1.1.2
Verifying the configuration
# Display RPF information for Source on Switch B.
[SwitchB] display multicast rpf-info 50.1.1.100
RPF information about source 50.1.1.100:
RPF interface: Vlan-interface101, 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 information:
•
The RPF route on Switch B is the configured static multicast route.
•
The RPF neighbor of Switch B is Switch C.

Creating an RPF route

Network requirements
As shown in
•
PIM-DM runs on the network.
•
All switches on the network support IP multicast.
•
Switch B and Switch C run OSPF, and have no unicast routes to Switch A.
•
Typically, the receiver host receives the multicast data from Source 1 in the OSPF domain.
Configure the switches so that the receiver host receives multicast data from Source 2, which is
outside the OSPF domain.
