The Cisco® XR 12000 and 12000 Series Performance Route Processor-2 (PRP-2) is the next-generation route processor for allCisco 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.
The Cisco PRP-2 (Figure 1) 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
