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.
Figure 1-2
shows a bridge acting as a root
unit on a wired LAN communicating with other non-root bridges on remote LANs.

, packets sent between the file server and Workstation B or Workstation C go through the
non-root bridges over the wireless link. Data packets sent from Workstation A to the file server go
through the wired LAN segment and do not go across the wireless link.
