43.6.4 PIM-SSM Troubleshooting

In configuring and using PIM-SSM Protocol, PIM-SSM Protocol might not operate normally caused by

physical connection or incorrect configuration. Therefore, the user should pay attention to the following

issues:

 Assure that physical connection is correct;
 Assure the Protocol of Interface and Link is UP (use show interface command);
 Assure that PIM Protocol is enabled in Global Mode (use ip pim multicast-routing);
 Assure that PIM-SSM is configured on the interface (use ip pim sparse-mode);
 Assure that SSM is configured in Global Mode;
 Multicast Protocol requires RPF check using unicast routing, therefore the correctness of unicast

routing must be assured beforehand.
