An RP cannot join an SPT in PIM-SM
Symptom
An RPT cannot be correctly built, or an RP cannot join the SPT toward the multicast source.
Solution
To resolve the problem:
Use display ip routing-table to verify that a unicast route to the RP is available on each router.
Use display pim rp-info to verify that the dynamic RP information is consistent on all routers.
Use display pim rp-info to verify that the same static RPs are configured on all routers on the network.
