  • Page 2: Important Information

    PRP Redundancy When two PRPs are installed in a Cisco XR 12000 Series Router, one PRP is the active PRP and the other is a backup, or standby, PRP. If the active PRP fails or is removed from the system, the standby PRP detects the failure and initiates a switchover.

  • Page 3: Product Overview

    ETH 2 PERFORMANCE ROUTE PROCESSOR 2 The PRP-2 is available as product number PRP-2 or PRP-2=, which includes one PRP with 1 G of synchronous dynamic random-access memory (SDRAM) and one 64-MB advanced technology attachment (ATA) Flash disk. A redundant PRP (product number PRP-2/R) is also available.

    Flash memory also functions as a Trivial File Transfer Protocol (TFTP) server to allow other servers to boot remotely from stored images or to copy them into their own Flash memory. The onboard Flash memory (called bootflash) contains the Cisco IOS boot image, and the Flash disk contains the Cisco IOS software image.

    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.
