Figure 23 Bridging Example; Figure 24 Bridge Loop: Two Bridges Connected To Hub - ZyXEL Communications ZYAIR G-5100 User Manual

ZyAIR G-5100 User's Guide
In the example below, when both ZyAIRs are in Bridge/Repeater mode, they form a WDS
(Wireless Distribution System) allowing the computers in LAN 1 to connect to the computers
in LAN 2.

Figure 23 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.
