The configuration on Device C is similar to the configuration on Device A. The specific configuration steps
are omitted here.
# Use the display multicast rpf-info command to view the RPF route to Source on Firewall B.
[FirewallB] display multicast rpf-info 50.1.1.100
RPF information about source 50.1.1.100:
RPF interface: GigableEthernet0/3, 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
As shown above, the current RPF route on Firewall B is contributed by a unicast routing protocol and the
RPF neighbor is Device A.
3. Configure a multicast static route
# Configure a multicast static route on Firewall B, specifying Device C as its RPF neighbor to Source.
[FirewallB] 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 information about the RPF route to Source on
Firewall B.
[FirewallB] display multicast rpf-info 50.1.1.100
RPF information about source 50.1.1.100:
RPF interface: GigabitEthernet0/2, 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
As shown above, the RPF route on Firewall B has changed. It is now the configured multicast static route,
and the RPF neighbor is now Device C.
Example for creating an RPF route
Network requirements
• PIM-DM runs in the network and all devices in the network support IP multicast.
• Firewall B and Firewall C run OSPF, and have no unicast routes to Device 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.
