How to Configure Multi-Point Wireless Bridging

Figure 5-5: Multi-Point bridging

Configure the Operating Mode of the WAG102 Access Points.

WAG102 (AP1) on LAN Segment 1 in Point-to-Point Bridge mode with the Remote MAC Address of AP2.
Because it is in the central location, configure WAG102 (AP2) on LAN Segment 2 in Point-to-Multi-Point Bridge mode. The MAC addresses of the adjacent APs are required in AP2.
Configure the WAG102 (AP3) on LAN 3 in Point-to-Point Bridge mode with the Remote MAC Address of AP2.

Verify the following parameters for all access points:

Verify that the LAN network configuration the WAG102 Access Points are configured to operate in the same LAN network address range as the LAN devices
Only one AP is configured in Point-to-Multi-Point Bridge mode, and all the others are in Point-to-Point Bridge mode.
All APs must be on the same LAN. That is, all the APs LAN IP address must be in the same network.
If using DHCP, all WAG102 Access Points should be set to "Obtain an IP address automatically (DHCP Client)" in the IP Address Source portion of the Basic IP Settings menu.
All WAG102 Access Points use the same SSID, Channel, authentication mode, if any, and encryption in use.
All Point-to-Point APs must have AP2's MAC address in its Remote AP MAC address field.

Verify connectivity across the LANs.

A computer on any LAN segment should be able to connect to the Internet or share files and printers with any other PCs or servers connected to any of the three LAN segments.

Wireless stations will not be able to connect to the WAG102 Access Points in the illustration above. If you require wireless stations to access any lan segment, you can additional WAG102 Access Points configured in Wireless Access Point mode to any LAN segment.

How to configure Point to Multi-Point Networks

Description:

Point to multi-point networks are used to connect one location to one or more remote locations. The above diagram shows three connected multi-user networks (using a Hub or Switch). Any location may be configured as a Direct connection (without a Hub or Switch).
Air-Frame 100 at location B can be used to create many, co-located point to multi-point networks or cells.

Typical Applications:

Internet, Intranet or Extranet configurations. ISP access networks. LAN to LAN applications (bridged or routed see below). Remote data capture (Telemetry or SCADA). Remote Control. Remote Monitoring, Security, Hub and Spoke, Conferencing.

Bridged or Routed:

In a bridged connection (Air-Frame 10 or 100 range) the network traffic is sent from one location to all other locations and consists of:

Traffic for a PC or system on any other network i.e. traffic from location A to, say, a system at location B, is also received by Location C (but is only sent once over the radio) and is placed on the local LAN at C by the bridging function.
Broadcast traffic (e.g. network management).
Multicast traffic.

In effect all the locations operate as a single, fully transparent LAN. Where one or more locations consist of many PCs or systems the broadcast traffic alone can be considerable and consideration should be given to using a routed network. In addition the redundant traffic received at each location can stress the local LAN network and cause security concerns. In this case also a routed solution should be considered.
In a routed connection (Air-Frame 100 range) the traffic is sent from one location to all other Locations consists and consists only of:

Traffic for a PC or system on any other network i.e. traffic from location A to, say, a system at location B, is also received by Location C (but is only sent once). The routing function however prevents this redundant traffic from being placed on the local LAN at C.

In this configuration the LANs operate independently but communication is enabled between them.

Inter-working:

The following defines inter-working between the Air-Frame Family:

Location A	Location B & C
Air-Frame 10.1	Air-Frame 10.1
Air-Frame 10.2	Air-Frame 10.2 Air-Frame 100 (any model)
Air-Frame 100 (any model)	Air-Frame 10.2 Air-Frame 100 (any model)
