An example of using WDS router interfaces to achieve a similar physical topology to the WDS
bridge example discussed earlier is illustrated below. In both examples, there are four WDS Access
points each with the possibility of having their own client/stations associated. In both examples A,
B, C, and D can all exchange data with each other. The bridged example has the advantage of
redundancy but at the expense of extra overhead. The routed example below cannot provide the
redundancy of the bridged example, and requires more configuration effort, but does not have the
overhead of using the bridge Spanning Tree Protocol, so is suited to fixed installations that do not
require redundancy.
As mentioned previously, configuration of the WDS router example is more complex than the
bridged example given earlier. In this case, all Access Points have different SSID’s and none of
them have SSID broadcast disabled so that WDS configurations can be made without knowledge of
Access Point MAC addresses. If SSID broadcasts were disabled, each configuration entry would
require an SSID
and
a MAC address (this is because both SSID
and
MAC addresses are required to
