highly available and redundant. The core area can also connect to Internet resources. The core aggregates the traffic from all the distribution layer devices‚ so it must be capable of forwarding large amounts of data quickly. Distribution - The distribution layer aggregates the data received from the access layer switches before it is transmitted to the core layer for routing to its final destination. The distribution layer controls the flow of network traffic using policies and delineates broadcast
