Turn on BSR debugging to view bootstrap messages:

-> ip pimsm debug-type bootstrap

-> ip pimsm debug-level 100

tPimsm-:     Received bootstrap message from 192.168.11.1, bsr addr:192.168.13.1 
on vlan 2
tPimsm-:        RPF check failed for bootstrap msg. SA: 192.168.11.1,BSR 
:192.168.13.1, vlan 2
tPimsm-:        pimsmBSRStateTransition - Entering with Event TMR  State : ELCTD

An IP unicast routing issue causes this; the receiving router does not have a route entry for 192.16811.1. 

-> show ip pimsm rp-candidate

This is caused by a missing C-RP address
