CLI Reference Guide
To configure the router to advertise itself as a Protocol Independent Multicast (PIM)
Version 2 candidate rendezvous point (RP) to the bootstrap router (BSR), use the ip
pim rp-candidate command in global configuration mode. To return default, use the
no form of this command. If no parameter is added in no command, the device will
restore default value for interval of CRP-Adv and priority of CRP interface. If interface
name added in no form of this command, the device will clean the ACL information
binding on this interface.
Interface name. The IP address associated with this interface is advertised as a
candidate RP address.
The name of access list. If no group-list is specified, the switch is a candidate RP
for all groups.
Specify interval of sending CRP-Adv message to BSR,. The range is 0 to 102.
Specify the priority of this CRP interface, in the range 0 to 255.
Specify the Prefix Count value of the wildcard address (224.0.0.0/24) to be set to 0 in
PIM C-RP-Adv message.
Specify that the wildcard prefix count value will be set to 1 in PIM C-RP-Adv message.
No candidate RP is configured. The default CRP-Adv interval is 60 seconds. The
default priority value is 192. The default wildcard prefix count is 0.
Global configuration mode
This command is used to configure candidate RP information of PIM. The change of
CRP-Adv interval would also change the hold time of the CRP at the RP. The hold
time at RP is CRP-Adv interval multiplied by 2.5.
It is possible to have the cast, multiple CRP mapping to the same groups. At this
situation, the method below is used.
1. Perform longest match on group-range to obtain a list of RPs.
2. From this list of matching RPs, find the one with highest priority. Eliminate
any RPs from the list that have lower priorities.
3. If only one RP remains in the list, use that RP.
4. If multiple RPs are in the list, use the PIM hash function to choose one.
So, you can use this command to configure the priority of this CRP to specify the
sequence to select the RP for the groups.
This command can cause the router to send a PIM Version 2 message advertising
itself as a candidate RP to the BSR and set the parameter of this CRP. To specify an
