Enabling High Availability Features

To configure RPR and RPR+, use the following commands beginning in privileged EXEC configuration

 

 

mode:

 

 

 

 

 

 

 

 

 

 

Command

Purpose

 

Step 1

 

 

 

Router# configure terminal

Enters global configuration mode.

 

Step 2

 

 

 

Router(config)# hw-module slot slot-numberimage file-spec

Specifies the image to be used by the active RSP at

 

 

 

initialization. If a high-availability image is found,

 

 

 

the running configuration is updated.

 

 

 

slot-number—Specifies the active RSP slot

 

 

 

where the Flash memory card or Flash Disk is

 

 

 

located. Valid numbers are slot 2 or slot 3 for a

 

 

 

Cisco 7507 router or slot 6 or slot 7 for a Cisco

 

 

 

7513 router.

 

 

 

file-spec—Indicates the flash device and the

 

 

 

name of the image on the active RSP.

 

 

 

Note Step 2 and Step 3 are the same; Step 2

 

 

 

applies to the active RSP and Step 3 applies

 

 

 

to the standby RSP.

 

Step 3

 

 

 

Router(config)# hw-module slot slot-numberimage file-spec

Specifies the image to be used by the standby RSP

 

 

 

at initialization. If a high-availability image is

 

 

 

found, the running configuration is updated.

 

 

 

slot-number—Specifies the standby RSP slot

 

 

 

where the Flash memory card or Flash Disk is

 

 

 

located. Valid numbers are slot 2 or slot 3 for a

 

 

 

Cisco 7507 router or slot 6 or slot 7 for a Cisco

 

 

 

7513 router.

 

 

 

file-spec—Indicates the Flash device and the

 

 

 

name of the image on the standby RSP.

 

 

 

Note Step 2 and Step 3 are the same; Step 2

 

 

 

applies to the active RSP and Step 3 applies

 

 

 

to the standby RSP.

 

Step 4

 

 

 

Router(config)# redundancy

Enters redundancy configuration mode.

 

Step 5

 

 

 

Router(config-red)# mode rpr (Or mode rpr-plus)

Sets the redundancy mode to RPR (or RPR+) on

 

 

 

both the active and standby RSPs. HSA is the

 

 

 

default redundancy mode.

 

Step 6

 

 

 

Router(config-red)# exit

Exits redundancy configuration mode and returns

 

 

 

you to global configuration mode.

 

Step 7

 

 

 

Router(config)# end

Exits global configuration mode and returns you to

 

 

 

privileged EXEC configuration mode.

 

Step 8

 

 

 

Router# hw-module sec-cpu reset

Resets and reloads the standby RSP with the

 

 

 

specified Cisco IOS image and executes the image.

 

 

 

Note If you do not specify a Cisco IOS image in

 

 

 

Step 2, this command loads and executes

 

 

 

the bundled default IOS standby image.

 

 

 

The system then operates in HSA mode.
