Configuring External Control Plane
In Cisco routers, the route processor (RP) that runs the control plane is hosted in the router chassis along with line cards. Hence, there is a tight coupling of control and data planes. Cisco NCS 6000 supports running up to three SDRs on the same RP. With the external control plane (ECP) feature, two external servers are connected to the NCS 6000 chassis through the control ethernet. This ensures control plane reachability across the NCS 6000 chassis and both the servers and provides the additional system resources that are required to scale beyond the current restriction of three named SDRs.
