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
Group Address RP Address Status

227.1.1.1/32 192.168.12.2 disabled
226.1.1.1/32 192.168.12.2 disabled

This is caused by a missing C-RP address

-> show ip pimsm

BSR Address = 192.168.13.1,
BSR Expiry Time = 00h:01m:21s,
CBSR Address = 0.0.0.0,
