5.4 Configuring Bridge
The ZyAIR can function as a wireless network bridge allowing you to wirelessly connect two wired network
segments. You need to know the MAC address of the peer device, which also must be in bridge mode.
In the example below, Computers B and C will be able to communicate with Computer A through the ZyAIR
bridges, forming a Wireless Distribution System (WDS).
Figure 5-6 Bridging Example
Be careful to avoid bridge loops when you enable bridging in the ZyAIR. Bridge loops cause broadcast
traffic to circle the network endlessly, resulting in possible throughput degradation and disruption of
communications. The following examples show two network topologies that can lead to this problem:
If two or more ZyAIRs (in bridge mode) are connected to the same hub as shown next.

If your ZyAIR (in bridge mode) is connected to a wired LAN while communicating with another
wireless bridge that is also connected to the same wired LAN as shown next.
