Cisco XR 12000 and 12000 Series Performance Router Processor-2
The Cisco® XR 12000 and 12000 Series Performance Route Processor-2 (PRP-2) is the next-generation route processor for all Cisco XR 12000 and 12000 series routers. The Cisco PRP-2 offers up to 100-percent performance improvement on most system tasks, up to 4 GB of memory, a Gigabit Ethernet management port, and a hard drive option. The Cisco PRP-2 delivers the scalability needed for service and network convergence. It also provides a Building Integrated Timing Supply (BITS) interface, a component of the Cisco XR 12000 and Cisco 12000 series BITS architecture that will enable network service synchronization on the platform in the future.
Product Overview
The Cisco PRP-2 is the next-generation route processor for the Cisco XR 12000 and 12000 series routers, addressing the unique route processing requirements of carrier-grade IP and Multiprotocol Label Switching (MPLS) packet infrastructures. It is responsible for the following functions:
-Executing routing protocol stacks.
-Performing all protocol communications with other routers.
-Building and distributing forwarding information to all line cards.
-Uploading the operating system software system images to all installed line cards upon powering up.
-Providing out-of-band system console and auxiliary ports and an Ethernet port for router configuration and maintenance.
-Monitoring and managing the power and temperature of system components such as line cards, power supplies, and fans.
The Cisco PRP-2 delivers all these functions with enhanced performance and capabilities. It also delivers the following feature enhancements (depending on the software version running):
-Gigabit Ethernet management port.
-Hard-drive support (optional part).
-BITS input ports.
-Up to 4 GB compact image Flash memory support (optional part).
-Memory scalability up to 4 GB.
The Cisco XR 12000 and 12000 series routers are a portfolio of intelligent routing solutions that scale from 2.5 to n x 10 Gbps/slot capacity, enabling carrier-class IP/MPLS networks and accelerating the evolution toward IP Next-Generation Networks. Built upon a foundation of investment protection, this portfolio delivers up to 1.28 terabits per second switching capacity with wire-speed feature performance, scalability, and graceful hardware and software upgrade paths.
