Enabling auto-RP
Auto-RP announcement and discovery messages are addressed to the multicast group addresses
224.0.1.39 and 224.0.1.40, respectively. With auto-RP enabled on a device, the device can receive
these two types of messages and record the RP information carried in such messages.

Configuring C-RP timers globally
To enable the BSR to distribute the RP-set information within the BIDIR-PIM 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 in the network.
Each C-RP encapsulates a timeout value in its C-RP-Adv messages. After receiving a C_RP-Adv 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 within the timeout interval, the BSR assumes the C-RP to have expired
or become unreachable.
The C-RP timers need to be configured on C-RP routers.
