7.5 PIM Troubleshooting

Fault: The router fails to establish the multicast routing table.
Troubleshooting: Follow the steps below:
Make sure that the unicast routes are correct before settling to the problem.
PIM-SM requires support from the RP and the BSR. Use the display pim bsr-info
command to check for BSR information. If none, check for the unicast routes
towards the BSR. Then use the display pim rp-info command to check for RP
information. If none, also check the unicast routes.
Use the display pim neighbor command to check whether the neighbor
relationship has been established correctly.
