Make sure that the unicast routing is right before troubleshooting PIM.
z Because PIM-SM needs the support of RP and BSR, you must execute the
display pim bsr-info command to see whether BSR information exists. If not, you
must check whether there are unicast routes to the BSR. Then use the display
pim rp-info command to check whether the RP information is right. If RP
information does not exist, you must check whether there are unicast routes to RP.
z Use the display pim neighbor command to check whether the neighboring
relationship is correctly established.
