IV. Configuring C-RP timers
To enable the BSR to distribute the RP-set information within the PIM-SM domain,
C-RPs must periodically send C-RP-Adv messages to the BSR. The BSR learns the
RP-set information from the received messages, and encapsulates its own IP address
together with the RP-set information in its bootstrap messages. The BSR then floods
the bootstrap messages to all PIM routers (224.0.0.13) in the network.
Each C-RP encapsulates a timeout value in its C-RP-Adv message. Upon receiving
this message, the BSR obtains this timeout value and starts a C-RP timeout timer. If the
BSR fails to hear a subsequent C-RP-Adv message from the C-RP when the timer
times out, the BSR assumes the C-RP to have expired or become unreachable.
Follow these steps to configure C-RP timers:
