Configuring the Candidate RPs
You can configure one or more candidate RPs. Similar to BSRs, the RPs should also have good connectivity
to other devices and be in the backbone portion of the network. An RP can serve the entire IP multicast address
space or a portion of it. Candidate RPs send candidate RP advertisements to the BSR. When deciding which
devices should be RPs, consider these options:
•
In a network of Cisco routers and multilayer switches where only Auto-RP is used, any device can be
configured as an RP.
•
In a network that includes only Cisco PIMv2 routers and multilayer switches and with routers from other
vendors, any device can be used as an RP.
•
In a network of Cisco PIMv1 routers, Cisco PIMv2 routers, and routers from other vendors, configure
only Cisco PIMv2 routers and multilayer switches as RPs.
This procedure is optional.
SUMMARY STEPS
1.
configure terminal
2.
ip pim rp-candidate interface-id [group-list access-list-number]
3.
access-list access-list-number {deny | permit} source [source-wildcard]
4.
end
5.
show running-config
6.
copy running-config startup-config
DETAILED STEPS
PurposeCommand or Action
Enters the global configuration mode.configure terminal
Example:
Switch# configure terminal
Step 1
Configures your switch to be a candidate RP.
ip pim rp-candidate interface-id [group-list
access-list-number]
Step 2
•
For interface-id, specify the interface whose associated IP address
is advertised as a candidate RP address. Valid interfaces include
physical ports, port channels, and VLANs.
Example:
Switch(config)# ip pim rp-candidate
•
(Optional) For group-list access-list-number, enter an IP standard
access list number from 1 to 99. If no group-list is specified, the
switch is a candidate RP for all groups.
gigabitethernet 1/0/5 group-list 10
To remove this device as a candidate RP, use the no ip pim
rp-candidate interface-id global configuration command.
