Explanation:
Control Plane Policing (CoPP) is a Cisco IOS-wide feature designed to allow users to manage the
flow of traffic handled by the route processor of their network devices. CoPP is designed to
prevent unnecessary traffic from overwhelming the route processor that, if left unabated, could
affect system performance. Route processor resource exhaustion, in this case, refers to all
resources associated with the punt path and route processor(s) such as Cisco IOS process
memory and buffers, and ingress packet queues.
