Explanation
The control plane is responsible for building and maintaining the information used to make forwarding decisions. This includes all routing protocol traffic (OSPF hello packets, BGP updates, EIGRP queries, etc.) that routers exchange to populate their routing and forwarding tables. The data plane (forwarding plane) uses those tables to forward actual user traffic at high speed. The management plane handles device administration traffic such as SSH, SNMP, and NetFlow. 'Authentication plane' is not a recognized standard network plane.
