In this way whole valid control plane traffic gets through but some flows slower that others.Ĭontrol Plane Protection extends QoS feature to the control plane by considering the Route Processor to be additional virtual interface attached to the router.
We can use QoS techniques in the entrance to Router Processor (showed in the image above), enabling us to drop or even better, to throttle some less important control traffic flows. Some other less important control traffic will be dropped on the entrance to control plane or slowed down by using buffering.

In that case, we can filter traffic based on predefined priority classes that we are free to define based on our specific traffic pattern.īy using CoPP, we can make a part of control plane traffic prioritised so that it can be efficiently processed by control plane in timely manner. Usage of Control Plane Protection is important on routers receiving heavy traffic of which to many packets are forwarded to Control Plane. BGP service is generating control plane traffic, sending that traffic to BGP neighbour and receiving control plane traffic back from the neighbour.
When router is making BGP neighbour adjacency with the neighbouring router, it means that both routers are running BGP protocol service on them. Control Plane Policing is QoS applied on ingress sub-interfacess towards Route Processor
