WLA Series Network Configurations
Wireless Bridge Configuration
You can use WLAN mesh services in a wireless bridge configuration, with the WLA620,
WLA622 or WLA632 units serving as bridge endpoints in a transparent Layer 2 bridge.
A typical application of wireless bridging is to provide network connectivity between two
buildings using a wireless link, as shown in the following illustration.
Figure 2–3. Point-to-Point Wireless Bridge Topology
The wireless bridge is established between a Mesh Portal WLA and a Mesh WLA to
which it is associated. The data packets that are bridged are those present on the
Ethernet interfaces of the two WLAs. A Mesh WLA serving as a bridge endpoint picks
up packets from a wired port and transfers them to the other bridge endpoint. A simple
source/destination learning mechanism is used to avoid forwarding packets across the
bridge unnecessarily.
A Mesh Portal WLA serving as a bridge endpoint can support up to five Mesh WLAs
serving as bridge endpoints in a point-to-multipoint configuration.
