Network Configuration Examples
This section describes the bridge's role in three common wireless network configurations. The bridge's
default configuration is as a root unit on a wired LAN. The other examples illustrate the bridge being
used as a repeater unit and as an access point.
Root Unit on a Wired LAN
The typical bridge configuration consists of two or more bridges. One bridge is connected directly to the
main wired LAN (referred to as a root unit) and the other bridge or bridges (referred to as non-root units)
are attached to remote LAN segments (usually in different buildings). Only one bridge in a wireless LAN
can be set to root, all other bridges must be set to non-root.
