5. On Switch C, configure a static multicast route, specifying the RPF neighbor toward the source as
interface Tunnel 0 on Switch A.
[SwitchC] ip rpf-route-static 50.1.1.0 24 50.1.1.1
Verifying the configuration
The source sends the multicast data to the multicast group 225.1.1.1 and the receiver host can receive the
multicast data after joining the multicast group. You can use the display pim routing-table command to
display PIM routing table information. For example:
# Display PIM routing table information on Switch C.
[SwitchC] display pim routing-table
Total 1 (*, G) entry; 1 (S, G) entry

The output shows that Switch A is the RPF neighbor of Switch C and the multicast data from Switch A is
delivered over a GRE tunnel to Switch C.
