The Cisco® Carrier Routing System (CRS) Performance Route Processor is the next-generation route processor for the Cisco CRS-1 and CRS-3 platforms. It is the first Cisco CRS Route Processor to offer the amazing speed of the Intel Xeon Dual-Core processor (Nehalem family). With 6 GB or 12 GB of fast double data rate 3 (DDR3) error correcting code (ECC) memory, the Performance Route Processor provides extremely fast routing performance at exceptional scale for the largest core and edge applications. The multicore design and speed allows you to achieve high levels scale for all applications such as Border Gateway Protocol (BGP) and Interior Gateway Protocols (IGP), Multiprotocol Label Switch Traffic Engineering (MPLS-TE), NetFlow, Lawful Intercept, Simple Network Management Protocol (SNMP) or Extensible Mark-up Language (XML) monitoring without adversely affecting routing performance.
