49.2.4 PIM-SM6 Troubleshooting
When configuring and using PIM-SM protocol, PIM-SM 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);
 Unicast route shall be used to carry out RPF examination for multicast protocol. So the correctness of
unicast route shall be guaranteed above all.
 PIM-SM Protocol requires supports of RP and BSR, therefore you should use show ipv6 pim bsr-router
first to see if there is BSR information. If not, you need to check if there is unicast routing leading to BSR.
 Use show ipv6 pim rp-hash command to check if RP information is correct; if there is no RP information,
you still need to check unicast routing;
If all attempts fail to solve the problems on PIM-SM, then use debug commands such as debug ipv6 pim/
debug ipv6 pim bsr, copy DEBUG information in 3 minutes and send to Technology Service Center.
