Command
show ip pim tunnel [tunnel | verbose]
show ip pim vrf { word { all-vrfs | autorp |
boundary | bsr-router | interface | mdt | neighbor
| rp | rp-hash | tunnel } }

Monitoring RP Mapping
Use the privileged EXEC commands in the following table to monitor RP mapping.
Table 9: RP Mapping Monitoring Commands
Command
show ip pim bsr
show ip pim bsr-router
show ip pim rp [ hostname or IP address | mapping
[ hostname or IP address | elected [hostname or IP
address] | in-use [hostname or IP address] ] | metric
[ hostname or IP address ] ]
show ip pim rp-hash hostname or IP group address

Troubleshooting PIMv1 and PIMv2 Interoperability Problems

When debugging interoperability problems between PIMv1 and PIMv2, check these in the order shown:
1 Verify RP mapping with the show ip pim rp-hash privileged EXEC command, making sure that all
systems agree on the same RP for the same group.
2 Verify interoperability between different versions of DRs and RPs. Make sure that the RPs are interacting
with the DRs properly (by responding with register-stops and forwarding decapsulated data packets from
registers).
