Configuration Scenarios

21.2 Network Topology: Wireless Bridge

This section describes several main types of installations commonly implemented using the ZyAIR. This is
by no means intended to be an exhaustive list of all possible configurations, but rather shows examples of
some of the more common implementations. The Wireless Bridge can be configured into two roles:

Central Wireless Router/Bridge

and

Remote Wireless Router/Bridge

to setup the broadband wireless

point-to-multipoint systems, see

Figure 2

of the

Quick Installation Guide

for bridging application.

Both the

Central Wireless Router/Bridge

and the

Remote Wireless Router/Bridge

can function in router

or bridge modes. In a Point-to-Multipoint topology, all communication between network systems is done
through a centralized agent. In the Outdoor Wireless Router/Bridge product, the centralized agent is a

Central Wireless Router

or

Central Wireless Bridge

and the individual network nodes may be

Remote

Wireless Router

or

Remote Wireless Bridge

.

To show some possibilities of Point-to-Multipoint topologies, the following examples are provided:

Remote Wireless Bridge-to-Central Wireless Bridge

Remote Wireless Router-to-Central Wireless Bridge

Remote Wireless Bridge-to-Central Wireless Router

Remote Wireless Router-to-Central Wireless Router

21.2.1

Configure the ZyAIR

The ZyAIR can be configured into two operation roles:

Central Wireless Router/Bridge

and

Remote Wireless Router/Bridge

.

Central Wireless Router/Bridge can be configured in four operation modes

Central Wireless Bridge

Central Wireless Router with PPP over Ethernet (PPPoE)

Central Wireless Router with Dynamic IP Address (DHCP Client)

Central Wireless Router with Static IP Address (Fixed IP)

Remote Wireless Router/Bridge can perform in two operation modes:

Remote Wireless Bridge

Remote Wireless Router

The ZyAIR is shipped with default configuration is as a bridge between an Ethernet and wireless network.
Users simply need to attach the ZyAIR to your wired LAN. If users would like to configure the ZyAIR,
please refer to the following procedures.
