BSR Address (pimComponentBSRAddress)

IP address of the bootstrap router (BSR) for the local PIM region.

BSR Expiry Time (pimComponentBSRExpiryTime)

Minimum time remaining before the BSR in the local domain is declared down. For candidate BSRs, this object indicates the amount of time before a component sends an RP-Set message. For other routers, this object indicates the amount of time a component waits before accepting an RP-Set message from a lower candidate BSR.

Candidate RP Hold Time (pimComponentCRPHoldTime)

Hold time of a component when it is a candidate RP in the local domain. The value "0" indicates that the local system is not a candidate RP.
