What Is an Aggregation Switch and How to Choose?
These aggregation switches typically operate at Layer 2 or Layer 3 of the OSI model, depending on the network topology and configuration requirements.

An aggregate switch consolidates traffic from access switches, while a core switch forms the backbone of the network, interconnecting multiple aggregate switches and providing access to

Aggregation layer switches aggregate data from multiple access switches and routes it to the core layer of the network. They provide inter-VLAN routing and advanced policies for handling

The following figure shows an aggregation-layer building block. Multiple blocks of pairs of aggregation switches extend the design of this key layer if there are more than 24 floors or buildings in the

Redundancy and High Availability: Deploy redundant core switches, use dynamic routing protocols (such as OSPF, BGP) and link aggregation (LACP) to enhance network reliability.

The aggregation layer serves as the convergence point for multiple access layer switches and is responsible for handling all the communication traffic from the access layer devices

Rather than having every access switch connect directly to the network backbone, the aggregation layer acts as a funnel. It takes high-bandwidth connections from below and routes them

Unlike the core switch, the aggregation switch can choose either the layer 2 switch or the layer 3 switch. When the layer 2 switches are selected, the routing and management strategy must
