At the same time, you should pay attention to the configuration of Unicast Routing Protocol, assure that each
devic e can communicate wit h each other in the network layer, and be able to implement dynamic routing
update in virtue of Unicast Routing Prot ocol.

43.3.4 PIM-SM Troubleshooting

In configuring and using PIM-SM Protocol, PIM-SM Prot ocol 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 Protoc ol is enabled in Global Mode (use ip pim multicast-routing);
 Assure that PIM-SM is configured on the interface (use ip pim sparse-mode);
 Multicast Protocol requires RPF Check using unicast routing; therefore the correctness of unicast
routing must be assured beforehand;
