Configuring static RP

Configure a static RP to ignore the bootstrap router (BSR) mechanism and use the statically configured RPs.

Before you begin

Enable PIM-SM globally.

About this task

Static RP-enabled switches use this feature to communicate with switches from other vendors that do not use the BSR.

Important

You cannot configure a static RP-enabled switch as a BSR or as a C-RP router.

All dynamically learned BSR information is lost. However, if you disable static RP, the switch loses the static RP information and regains the BSR functionality.

Procedure

Enter Global Configuration mode:

enable

configure terminal

Enable static RP:

ip pim static-rp

The following message appears:

WARNING: RP information learnt dynamically through BSR functionality will be lost.
Do you wish to enable Static RP? (y/n) ?

Enter y.
Configure a static RP entry:

ip pim static-rp {A.B.C.D/X} {A.B.C.D}
Configure all the switches in the network (including switches from other vendors) to map to the same RP.
Display information about the candidate rendezvous points for the PIM-SM domain:

show ip pim static-rp

Example

Configure a static RP:

Switch:1(config)#  ip pim static-rp 239.255.0.0/255.255.0.0 198.51.100.0

Variable definitions

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


Variable	Value
{A.B.C.D/X}	Specifies the IP address and address mask of the multicast group. When combined, the IP address and address mask identify the range of the multicast addresses that the RP handles.
{A.B.C.D}	Specifies the IP address of the static RP.
