Candidate-RPs (C-RPs) periodically send Advertisement messages to a BootStrap router (BSR). The Advertisement messages carry C-RP priorities. You can adjust the C-RP priority, the interval for sending Advertisement messages, and the holdtime of Advertisement messages on a device configured with the C-RP.
Before adjusting control parameters of the C-RP, complete the following tasks:
Configuring a unicast routing protocol
Perform the following steps on the FW configured with the C-RP:
You can re-set various parameters of a C-RP. This configuration is optional. If there is no specific requirement, default values of parameters are recommended.
pim [ vpn-instance vpn-instance-name ]
c-rp priority priority
c-rp advertisement-interval interval
c-rp holdtime interval
The value must be greater than the interval for a C-RP to send advertisement messages.
The C-RP periodically sends advertisement messages to the BSR. After receiving the advertisement messages, the BSR obtains the Holdtime of the C-RP from the message. During the Holdtime, the C-RP is valid. When the Holdtime expires, the C-RP ages out.
