Upgrading to the PRP

Note The PRP-2 does not require an RP ROM monitor upgrade before Cisco IOS Software Release 12.0(30)S. If you attempt this upgrade on a PRP-2 using a prior software release, you will receive the following error message:

Error: Unknown Flash Device type!

GRP ROM monitor upgrade won't continue

Upgrading the RP ROM Monitor Using Cisco IOS Release 12.0(24)S or Later

New functionality was introduced in Cisco IOS Software Release 12.0(24)S that enables the secondary RP to have its ROM monitor image upgraded while in standby mode, and does not require a reboot of the router. In order for this to work, the router must already be running Cisco IOS Software Release 12.0(24)S or later.

In the following procedure, RP1 is initially the active RP and RP2 is the standby RP.

Step 1 After you enter the configuration to load the new Cisco IOS software image, reload the standby PRP (RP2) using the hw-module standby reload command.

Step 2 Once the standby RP (RP2) is available again, use the upgrade rom-monitor slot sec-rp-slotcommand. If the routine finds that an upgrade is necessary, the new code will begin to be loaded. When this command is completed, reload the RP2 using the hw-module standby reload command.

Step 3 Switch over from the active PRP (RP1) to the standby PRP (RP2) using the redundancy force-switchovercommand. Once RP2 becomes active, the line cards will be reloaded.

Step 4 Let the router return to full operation with Interior Gateway Protocol (IGP) and Exterior Gateway Protocol (EGP) peers established (this may take a considerable amount of time, depending on the size and complexity of the router configuration).

Step 5 Check the line card CPU utilization using the execute-on all show proc cpu inc CPU command. If the CPU utilization has stabilized at the normal running level, proceed with the next step; otherwise, wait another five minutes and check again.
