    host1:1#show ip pim bsr
    
    This PIM router is a Candidate BSR.
      Configured on intf ATM3/0.101, address: 101.0.0.1
      hashMaskLen 30, priority 2, period 60 seconds.
    Elected BSR is this router, next BSM in 3 seconds.
    Local candidate RP mapping(s):
    Candidate RP 101.0.0.1
      224.0.0.0/4, BSR, hold-time 150, interval 60, priority 192
      228.0.0.0/24, BSR, hold-time 150, interval 60, priority 192, from access-list acl
      230.0.0.0/24, BSR, hold-time 150, interval 60, priority 192, from access-list acl

    To display information on a router that is a candidate BSR:

    host1:1#show ip pim bsr
    This PIM router is a Candidate BSR.
      Configured on intf ATM3/0.100, address: 100.0.0.1
      hashMaskLen 30, priority 2, period 60 seconds.
