Enabling High Availability Features

Verifying RPR and RPR+

Use the show redundancycommand to verify that RPR or RPR+ is enabled:

Router# show redundancy

Operating mode is sso

redundancy mode sso

hw-module slot 6 image disk0:rsp-pv-mz

hw-module slot 7 image disk0:rsp-pv-mz

Active High Availability version is 3.0

Standby High Availability version is 3.0

Active in slot 6

Standby in slot 7

The system total uptime since last reboot is 2 weeks, 23 hours 41 minutes.

The system has experienced 4 switchovers.

The system has been active (become master) for 21 hours 1 minute.

Reason for last switchover:User forced.

Configuring RPR and RPR+ Example

In the following example, the active RSP is in slot2 and the standby RSP is installed in slot 3 of a

Cisco 7507 router.

Router# copy tftp slot0:rsp-pv-mz

Router# copy tftp slaveslot0:rsp-pv-mz

Router# configure terminal

Router(config)# hw-module slot 2 image slot0:rsp-pv-mz

Router(config)# hw-module slot 3 image slot0:rsp-pv-mz

Router(config)# redundancy

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

Router(config-red)# exit

Router(config)# end

Router# hw-module sec-cpu reset

Router# show running-config
