3. Mesh Networking Overview
AP-5131's new mesh networking functionality
As a bridge to connect two Ethernet networks.
As a repeater to extend your network's coverage area without additional cabling.
The AP-5131 mesh networking functionality is configurable in two modes.
A wireless client bridge mode
A wireless base bridge mode  accepts connections from client bridges
These two modes are not mutually exclusive.
AP-5131s can be configured as a repeater
By configuring both a base and a client bridge function at the same time to transmit data
with associated MUs in their coverage area (client bridge mode) as well as forward traffic
to other AP-5131s in the mesh network (base bridge mode).
The number of AP-5131s and their intended function within the mesh network dictate
whether they should be configured as base bridges, client bridges or both (repeaters).

4. Mesh Networking Overview (contd)
In Client Bridge Mode
AP5131 scans to locate other access points using the WLAP client's ESSID.
Then it is required to go through the association and authentication process to
establish wireless connections with the located devices.
This association process is identical to the AP-5131's current MU association
process. Once the association and authentication process is complete, the
wireless client adds the connection as a port on its bridge module.
This causes the client bridge to begin forwarding packets to the base bridge node.
The base bridge realizes it is talking to a wireless client bridge.
It then adds that connection as a port on its own bridge module.
The two bridges at that point are communicating using the Spanning Tree Protocol (STP).
After the client bridge establishes at least one wireless connection (if configured to
support mobile users), it begins beaconing and accepting wireless connections.
If configured as both a client bridge and a base bridge, it begin accepting client bridge
connections.
Therefore, the mesh network could connect simultaneously to different networks in a
manner whereby a network loop is not created and then the connection is not blocked.
Once the client bridge establishes at least one wireless connection, it begins establishing
other wireless connections as it finds them available.
Thus, the client bridge is able to establish simultaneous redundant links.

5. Mesh Networking Overview (contd)
In Client Bridge mode
The client bridge creates up to three connections if it can find base bridges for connection.
If the connections are redundant (on the same network), then one connection will be
forwarding and the others blocked.
However, if each of the connections links to a different wired network, then none are
redundant and all are forwarding.
Thus, the bridge automatically detects and disables redundant connections, but leaves
non-redundant connections forwarding.
This gives the user the freedom to configure their topology in a variety of ways without
limitations.
This is important when configuring multiple AP-5131s for base bridge support in areas like
a shipping yard where a large radio coverage area is required
In Base Bridge Mode
AP5131 operates normally at boot time.
The base bridge supports connections made by other client bridge AP-5131s.
The dual-radio model AP-5131 affords users better optimization of the mesh networking
feature by enabling the AP-5131 to transmit to other mesh network members using one
independent radio and transmit with associated MUs using the second independent radio.
