III-1-6 WDS
WDS means Wireless Distribution System. It is a protocol for connecting two access points
(AP) wirelessly. Usually, it can be used for the following application:
 Provide bridge traffic between two LANs through the air.
 Extend the coverage range of a WLAN.
To meet the above requirement, two WDS modes are implemented in Vigor router. One is
Bridge, the other is Repeater. Below shows the function of WDS-bridge interface:
 
The application for the WDS-Repeater mode is depicted as below:
The major difference between these two modes is that: while in Repeater mode, the
packets received from one peer AP can be repeated to another peer AP through WDS links.
Yet in Bridge mode, packets received from a WDS link will only be forwarded to local wired
or wireless hosts. In other words, only Repeater mode can do WDS-to-WDS packet
forwarding.
In the following examples, hosts connected to Bridge 1 or 3 can communicate with hosts
connected to Bridge 2 through WDS links. However, hosts connected to Bridge 1 CANNOT
communicate with hosts connected to Bridge 3 through Bridge 2.
