To monitor the RP mapping information, use these commands in privileged EXEC mode: 

 displays information about the elected BSR.

 group displays the RP that was selected for the specified group.

 [group-name | group-address | mapping] displays how the switch learns of the RP 

(through the BSR or the Auto-RP mechanism).

When debugging interoperability problems between PIMv1 and PIMv2, check these in the order shown:

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.

Verify interoperability between different versions of DRs and RPs. Make sure the RPs are 
interacting with the DRs properly (by responding with register-stops and forwarding decapsulated 
data packets from registers).

By default, members of a group receive data from senders to the group across a single data-distribution 
tree rooted at the RP. 

 shows this type of shared-distribution tree. Data from senders is 

delivered to the RP for distribution to group members joined to the shared tree.
