H3C S5500-EI Series Ethernet Switches
[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
As shown above, the current RPF route on Switch B is contributed by a unicast routing
protocol and the RPF neighbor is Switch A.
3) Configure a multicast static route
# Configure a multicast static route on Switch B, specifying 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
4) Verify the configuration
# Use the display multicast rpf-info command to view the information about the RPF
route to 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
As shown above, the RPF route on Switch B has changed. It is now the configured
multicast static route, and the RPF neighbor is now Switch C.

9.5.2 Creating an RPF Route

I. Network requirements
PIM-DM runs in the network and all switches in the network support IP multicast.
Switch B and Switch C run OSPF, and have no unicast routes to Switch 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.
