Understanding PIM Shared Tree and Source Tree

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

show ip pim bsr displays information about the elected BSR.
show ip pim rp-hash group displays the RP that was selected for the specified group.
show ip pim rp [group-name | group-address | mapping] displays how the switch learns of the RP
(through the BSR or the Auto-RP mechanism).
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).
