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
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. |
