Upgrading to the PRP Without Rebooting the Router
To upgrade to the PRP from the GRP without interruption of service, you must have support for High
Availability in your router. This means that two GRPs must be installed in the router and the redundancy
must be set to either SSO or RPR+ mode. To configure the redundancy, use the redundancy command
in global configuration mode. To view the redundancy configuration on the RPs, use the show
redundancy command.
To upgrade to the PRP using High Availability, use the following procedure:
Verify that there are two GRPs in the router, both running the same Cisco IOS version, and that the router
Step 1
is configured for SSO or RPR+ redundancy. The show redundancy command indicates the redundancy
mode as well as the Cisco IOS version running on the GRPs. Take note of the Cisco IOS version running
on the GRPs (12.0(26)S in this example).
