API Guide

If you specify an access list, the C-RP advertises only the group range that the access list permits.
The no form of the command removes the router from being a C-RP. You must specify the parameters
with the no form of this command.

Command Mode CONFIGURATION
Usage
Information
Use this command to adjust the interval between candidate RP advertisements. The advertised RP
entries remain in the node until the hold time value expires. Dell EMC recommends configuring the hold
time value to be 2.5 times the advertisement interval. The no form of the command resets the candidate
RP timers to the default values.
Example
OS10# configure terminal
OS10(config)# ip pim vrf red rp-candidate-timers loopback 10 advt-
interval 30 hold-time 80
