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. When auto-RP is 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 must be configured on C-RP routers.
