Troubleshooting Examples: Limitations
Incorrect BSR ID
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
OperStatus UP
tPimsm-: BsrTimer Expired. Orig Message No State change
tPimsm-: pimsmBSRStateTransition - Leaving with Event TMR State : ELCTD
Status UP
tPimsm-: Sent BS on vlan 2 ipda = 224.0.0.13
An IP unicast routing issue causes this; the receiving router does not have a route entry for 192.16811.1.
Multicast Group Status is Shown as Disabled
-> show ip pimsm rp-candidate

226.1.1.1/32 192.168.12.2 disabled
This is caused by a missing C-RP address
