Bridge vs. Router
Each BU-945U-E is configured with an IP address for the Ethernet side, and another for the wireless side.
A Bridge connects devices within the same Ethernet network - for example, extending an existing Ethernet LAN. For a Bridge, the IP address for
the wireless side is the same as the Ethernet side.
A Router connects devices on different LANs.
The IP addresses for the Ethernet and wireless sides are different. In this example, the wireless link is part of LAN A, with the Client unit acting as
a Router between LAN A and LAN B.
Alternately, the Access Point could be configured as a Router - the wireless link is then part of LAN B.
If more than two routers are required within the same radio network, then routing rules may need to be configured (refer section 3.12 “ Routing
Rules” for further details). There is no limit to the number of Bridges in the same network - although there is a limit of 128 Client units linked to
any one Access Point.
