      PIM: *** Encoded-Unicast RP Address # 1 ***
      PIM: Address family = 1 (IP (IP version 4))
      PIM: Encoding type  = 0
      PIM: Unicast address = [192.168.12.2]
      PIM: RP1-Holdtime            = 150 (in seconds)
      PIM: RP1-Priority            = 0
      PIM: Reserved                 = 0
The RP-Holdtime parameters is the corresponding time the BSR will hold related RP multicast group 
information in its table as valid. This parameter is reset to 150 s when a C-RP Advertisement is received at 
BSR and originated by the RP in question.
Debugging RP-SET
As mentioned previously, RP-SET are included in Bootstrap messages. Commands to debug RP-SET:
-> ip pimsm debug-type bootstrap
-> ip pimsm debug-level 100
On Non BSR You Should See
tPimsm-:     Received bootstrap message from 192.168.12.1, bsr addr:192.168.13.1 
on vlan 2
tPimsm-:        AcceptBSMsg: Contents
tPimsm-:        AcceptBSMsg: Prefix : 225.1.1.1 Mask : 255.255.255.255
tPimsm-:        AcceptBSMsg: RP:  192.168.11.2 Priority : 0
tPimsm-:        AcceptBSMsg: current rplist does exist
tPimsm-:        AcceptBSMsg: removing timer
tPimsm-:        AcceptBSMsg: bit already set for indx:1
tPimsm-:        AcceptBSMsg: Prefix : 226.1.1.1 Mask : 255.255.255.255
tPimsm-:        AcceptBSMsg: RP:  192.168.12.2 Priority : 0
tPimsm-:        AcceptBSMsg: current rplist does exist
tPimsm-:        AcceptBSMsg: removing timer
tPimsm-:        AcceptBSMsg: bit already set for indx:2
tPimsm-:        AcceptBSMsg: Prefix : 227.1.1.1 Mask : 255.255.255.255
tPimsm-:        AcceptBSMsg: RP:  192.168.12.2 Priority : 0
tPimsm-:        AcceptBSMsg: current rplist does exist
tPimsm-:        AcceptBSMsg: removing timer
tPimsm-:        AcceptBSMsg: bit already set for indx:2
tPimsm-:        AcceptBSMsg: check Rehash
tPimsm-:        CheckRehash : SET adding rp:indx:1
tPimsm-:        CheckRehash : SET adding rp:indx:2
This output shows the IP address of the routing relaying the bootstrap message, the BSR ID, the VLAN 
ID, the various multicast group, RP IP address and priority.
Issuing the same command on the BSR would detail the C-RP Advertisement received, and the bootstrap 
messages sent on various interfaces.
