What is the purpose of this CoPP configuration?
- To rate-limit traffic destined to the router's control plane
- To filter traffic between interfaces
- To encrypt control plane communications
- To prioritize routing protocol traffic over management traffic
Explanation: According to the sources, the primary purpose of a Control Plane Policing (CoPP) configuration is to filter or rate-limit traffic that is specifically destined for the device's control plane (the CPU), .
By utilizing a policy map, administrators can define policing actions for various traffic classes—such as ICMP, routing protocols, or management sessions—imposing limits in bits per second, .
Traffic that conforms to these rates is permitted to the process level, while traffic that exceeds the limit is dropped, .
This mechanism protects the CPU from being overwhelmed by flooding attacks or excessive traffic, ensuring that critical functions like building routing tables and device management remain stable and responsive, .
