# On Device C, configure a static multicast route and specify its RPF neighbor leading toward Source is

Tunnel 0 on Device A.

[DeviceC] ip rpf-route-static 10.1.1.0 24 50.1.1.1

Step6

Verify 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 the devices using the
display pim routing-table command. For example:
# View the PIM routing table information on Device C.

[DeviceC] display pim routing-table

VPN-Instance: public net

Total 1 (*, G) entry; 1 (S, G) entry

(*, 225.1.1.1)

Protocol: pim-dm, Flag: WC

UpTime: 00:04:25

Upstream interface: NULL

Upstream neighbor: NULL

RPF prime neighbor: NULL

Downstream interface(s) information:

Total number of downstreams: 1

Protocol: igmp, UpTime: 00:04:25, Expires: never

(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: GigabitEthernet0/1

Protocol: pim-dm, UpTime: 00:04:25, Expires: never

As shown above, Device A is the RPF neighbor of Device C and the multicast data from Device A is

delivered over a GRE tunnel to Device C.

Troubleshooting Multicast Routing and Forwarding

Multicast Static Route Failure

Symptom

No dynamic routing protocol is enabled on the routers, and the physical status and link layer status of
interfaces are both up, but the multicast static route fails.
