Core: The core layer should be built from the highest performance switches in the network, aggregating traffic from the distribution switches. Layer 2 switches can be used effectively, although switching at Layer 3 adds higher availability and enhanced QoS. Usually a dual-switch core layer is sufficient to support an entire enterprise. Identify resources in your network that serve common functions. These become the modules or building blocks of your network design. Figure 2-2 shows some examples of these blocks and how they fit within the network hierarchy.
