Explanation

In legacy hierarchical network design, three key layers are used to create a scalable and structured network: The access layer is where end devices, such as computers and IP phones, connect to the network. It typically involves switches that provide connectivity for devices at the edge of the Aggregation Layer (Distribution Layer): The aggregation layer (also called the distribution layer) aggregates traffic from multiple access layer devices and applies policies such as filtering and QoS. It also provides redundancy and load The core layer provides high-speed connectivity between aggregation layer devices and facilitates traffic within the data center or between different network segments.
