Sh ip pim rp output
PE3#sh ip pim rp
Group: 235.235.235.235, RP: 10.1.1.3, v2, v1, next RP-reachable in 00:00:28
Group: 224.2.2.2, RP: 10.1.1.3, next RP-reachable in 00:00:34

the ones with v2,v1,next RP-reachable are the entries for which we are the RP.
But to tell if this was via static or Auto-RP, we have to do sh ip pim rp mappings
