Encryption levels and key above are shows as being different however they can be the same as in some of the earlier
examples. One reason why the Encryption level and key would be different is because the Access Point may have clients
that communicate using a different Encryption method e.g. 128 bit WEP and may not support the same Encryption
method.
Example 4
– WDS Routed Network
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.
