Configuring a candidate rendezvous point

Configure a candidate rendezvous point (C-RP) to serve as backup to the RP router.

About this task

You can configure only one interface on the switch for multiple groups. You cannot configure multiple interfaces for multiple groups.

With the mask value, you can configure a C-RP router for several groups in one configuration.

For example, if you use a C-RP configuration with a group address of 224.0.0.0 and a group mask of 240.0.0.0, you can configure the C-RP router for a multicast range from 224.0.0.0 to 239.255.255.255.

Procedure

Enter Global Configuration mode:

enable

configure terminal
Add a candidate rendezvous point:

ip pim rp-candidate group <A.B.C.D> <A.B.C.D> rp <A.B.C.D>
Remove a candidate rendezvous point:

no ip pim rp-candidate group <A.B.C.D> <A.B.C.D>
Display information about the candidate rendezvous points for the PIM-SM domain:

show ip pim rp-candidate

Example

Add a candidate rendezvous point:

Switch:1(config)#ip pim rp-candidate group 224.1.1.0 255.255.255.0 rp 198.51.100.0

Variable definitions

Use the definitions in the following table to use the ip pim rp-candidate command.


Variable	Value
group {A.B.C.D} {A.B.C.D}	Specifies the IP address and the address mask of the multicast group. After the IP address and group mask are combined, it identifies the prefix that the local router uses to advertise itself as a C-RP router.
rp {A.B.C.D}	Specifies the IP address of the C-RP router. This address must be one of the local PIM-SM enabled interfaces.
