rp-address

Configures a device interface as a static rendezvous point (RP) for IPv4 PIM.

Syntax

rp-address ip-address[group-range-prefix-list]

no rp-address ip-address

Command Default

The RP is selected by the PIM-SM (Sparse Mode) RP election process.

Parameters

ip-address: Specifies the IPv4 address of the RP.
group-range-prefix-list: Specifies the IPv4 multicast group range to be mapped to the RP. The default group range for IPv4 is 224/4.

Modes

Router PIM configuration mode

Usage Guidelines

Devices in the PIM-SM domain use the specified static RP and ignore group-to-RP mappings received from the bootstrap router (BSR).

The RP is the meeting point for PIM-SM sources and receivers. A PIM-SM domain can have multiple RPs, but each PIM-SM multicast group address can have only one active RP. PIM-SM routers learn the addresses of RPs and the groups for which they are responsible from one of the following sources.

The no rp-address form of this command restores the default functionality, in which the RP is selected by the RP election process.

Examples

This example configures the device interface at IP address 4.4.4.4 as the RP. The default group range is 224/4.

device(config)# router pim
device(config-pim-router)# rp-address 4.4.4.4

This example configures the RP with specific group ranges for IPv4.

device(config)# router pim
device(config-pim-router)# rp-address 4.4.4.4 static-rp-plist
device(config)# ip prefix-list static-rp-plist permit 225.1.1.0/24

This example configures the device interface at IPv6 address 1234::22 as the RP. The default group range is FF00::/8.

device(config)# ipv6 router pim
device(config-ipv6-router-pim-vrf-default-vrf)# rp-address 1234::22

This example configures the RP with specific group ranges for IPv6.

device(config)# ipv6 router pim
device(config-ipv6-router-pim-vrf-default-vrf)# rp-address 1234::22 group-range-plist1
device(config)# ipv6 prefix-list group-range-plist1 permit ff0e::/16
