Bridging
PathBuilder S200 series switches support bridging of data traffic for Ethernet LANs.
Bridging LAN traffic minimizes your networking costs by eliminating the need for
redundant networks and maximizes the availability of dedicated facilities such as
servers and printers, as well as public Frame Relay and X.25 services, across
multiple LANs.
PathBuilder S200 series switches are intended for use in remote bridging solutions.
This means the PathBuilder S200 series switch is best used to connect a remote LAN
to the WAN to connect to other remote LANs in your network, as shown in Figure 1.
