5. On Switch C, configure a static multicast route, specifying the RPF neighbor leading toward
Source as Tunnel 0 on Switch A.
[SwitchC] ip rpf-route-static 50.1.1.0 24 50.1.1.1
Verifying the configuration
Source sends multicast data to the multicast group 225.1.1.1 and Receiver can receive the
multicast data after joining the multicast group. You can view the PIM routing table information on
routers using the display pim routing-table command. For example:
# View the PIM routing table information on Switch C.
[SwitchC] display pim routing-table
VPN-Instance: public net
Total 1 (*, G) entry; 1 (S, G) entry
(*, 225.1.1.1)

(10.1.1.100, 225.1.1.1)
Protocol: pim-dm, Flag: ACT
UpTime: 00:06:14
Upstream interface: Tunnel0
Upstream neighbor: 50.1.1.1
RPF prime neighbor: 50.1.1.1
Downstream interface(s) information:
Total number of downstreams: 1
1: Vlan-interface200
Protocol: pim-dm, UpTime: 00:04:25, Expires: never
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.
