The Cisco® Carrier Routing System (CRS) performance route processors provide speed and scale for the evolving needs of the network. The Cisco CRS route processor comes with the speed of the Intel® Xeon® dual-core processor and has 6 or 12 GB of double data rate type three (DDR3) error-correcting code (ECC) memory for fast routing performance and exceptional scale for the largest core and edge applications. The multicore design and speed allow you to achieve high scaling levels for all applications, such as Border Gateway Protocol (BGP) and Interior Gateway Protocols (IGP), Multiprotocol Label Switch Traffic Engineering (MPLS-TE), Cisco NetFlow, Lawful Intercept, Simple Network Management Protocol (SNMP), or Extensible Mark-up Language (XML) monitoring, without adversely affecting routing performance.
