21.2.5 PIM-SM 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.
