CHAPTER 1
Campus Network Design
Small Campus Design
In a small campus, the core and distribution can be combined into one layer. Small is defined as fewer than 200 end
devices. In very small networks, one multilayer switch might provide the functions of all three layers. Figure 1-1 shows a
sample small network with a collapsed core.
Medium Campus Design
A medium-sized campus, defined as one with between 200 and 1000 end devices, is more likely to have several distribu-
tion switches and thus require a core layer. Each building or floor is a campus block with access switches uplinked to
redundant multilayer distribution switches. These are then uplinked to redundant core switches, as shown in Figure 1-2.
