Figure 52 Bridging Example

Be careful to avoid bridge loops when you enable bridging in the ZyXEL Device. 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 ZyXEL Devices (in bridge mode) are connected to the same hub.

Figure 53 Bridge Loop: Two Bridges Connected to Hub

• If your ZyXEL Device (in bridge mode) is connected to a wired LAN while

communicating with another wireless bridge that is also connected to the same wired
LAN.
