The configuration on Switch C is similar to the configuration on Switch A. The specific configuration
steps are omitted here.
# Use the display multicast rpf-info command to view 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-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.
