At the same time, you should pay attention to the configuration of Unicast Routing Protocol, assure that each
device can communicate with each other in the network layer, and be able to implement dynamic routing
update in virtue of Unicast Routing Protocol.
43.3.4 PIM-SM Troubleshooting
In configuring and using PIM-SM Protocol, PIM-SM 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-SM is configured on the interface (use ip pim sparse-mode);
