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

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

  1. Enter Global Configuration mode:

    enable

    configure terminal

  2. 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) ?
    
  3. Enter y.
  4. Configure a static RP entry:

    ip pim static-rp {A.B.C.D/X} {A.B.C.D}

  5. Configure all the switches in the network (including switches from other vendors) to map to the same RP.
  6. 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.
