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 SecPath C.
[SecPathC] display pim routing-table
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
The output shows that SecPath A is the RPF neighbor of SecPath C and the multicast data from
SecPath A is delivered over a GRE tunnel to SecPath C.
Troubleshooting static multicast 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 static multicast route fails.
Analysis
• If the static multicast route is not configured or updated correctly to match the current network
conditions, the route entry and the configuration information of static multicast route do not exist in
the multicast routing table.
• If a better route is found, the static multicast route might also fail.
