Point to point bridge connection
In this network, WDS uses two devices to form a bridge between two LANs, and interconnect the two
LANs. In actual applications, each device can determine the bridge connection to be set up by
configuring the MAC address of the peer device. As shown in
Figure 262 , a WDS bridge link is set up
between AP 1 and AP 2 to connect LAN segment 1 and LAN segment 2 to form a unified LAN. When
users in LAN segment 1 are to access resources of LAN segment 2, all packets are transformed into
wireless packets by AP 1 and sent to AP 2 through the wireless bridge link, restored on AP 2, and then
sent to the destination, and vice versa.

Point to multi-point bridge connection
In this topology, a device acts as the centralized device, and all the other devices set up wireless bridge
connections with only the centralized device, thus interconnecting multiple networks. This topology
conveniently connects multiple network islands to existing networks. However, all data exchanged
between each two branch networks is forwarded by the centralized device.

Mesh bridge connection
In this topology, multiple bridging devices can form mesh wireless bridge connections and interconnect
multiple LANs through manual configuration or self detection. In a mesh bridge network, when a WDS
link fails, backup links can take over. However, you must use STP to eliminate loops in actual
applications.
