5. Configure a static multicast route:
# On Firewall C, configure a static multicast route and specify its RPF neighbor leading toward
Source is Tunnel 0 on Firewall A.
[FirewallC] ip rpf-route-static 10.1.1.0 24 50.1.1.1
6. 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
firewalls by using the display pim routing-table command. For example:
# Display the PIM routing table information on Firewall C.
[FirewallC] display pim routing-table

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