21.1.5 PIM-DM Troubleshooting

When configuring and using PIM-DM protocol, PIM-DM protocol may fail to work
normally due to physical connections, incorrect configuration and so on. So, users shall
note the following points:
Assure the physical connection is correct.
Assure the Protocol of Interface and Link is UP (use show interface command);
Assure PIM Protocol is turned on in Global Mode (use ipv6 pim multicast-routing
command )
Start PIM-DM Protocol on the interface (use ipv6 pim dense-mode command)
Unicast route shall be used to carry out RPF examination for multicast protocol. So
the correctness of unicast route shall be guaranteed above all. If all attempts fail to solve
the problems on PIM-DM, then use debug commands such as debug ipv6 pim, copy
DEBUG information in 3 minutes and send to Technology Service Center.
