Upgrading to the PRP

• Turboboot Approach

• Pre-Staging Approach

Turboboot Approach

You can upgrade PRP-1 or PRP-2 with Cisco IOS XR software installed to PRP-3 using route processor

failover (RPFO). RPFO helps to minimize downtime and ensures service availability. To support RPFO

the PRP-1 or PRP-2 must have Cisco IO S XR Software Release 3.8.0 or a later release, which supports

PRP-3. To upgrade PRP-1 or PRP-2 with Cisco IOS XR software to PRP-3 execute the following steps:

Step 1 Remove the standby PRP-1 or PRP-2.

Step 2 Insert PRP-3 in the slot where standby PRP-2 has been removed.

Step 3 Turboboot PRP-3 with the Cisco IOS XR Software Release 3.8.0 or a later MBI (minimum boot image).

Step 4 After the standby PRP-3 is ready, perform a route processor fail over (RPFO) from PRP-1 or PRP-2 to

PRP-3.

Step 5 Double check if the configuration is correct and traffic resumes.

Step 6 Remove the standby PRP-1 or PRP-2 from the chassis after PRP-3 becomes an active RP.

Step 7 Insert the secondary PRP-3 board in the chassis.

Step 8 Turboboot and make the PRP-3 the new standby RP.
