EXP Computer S200 manual LAN Bridge Link

Configuring the PathBuilder S200 Series Switch for Bridging Operation

5)The PathBuilder S200 series switch transfers a copy of the ARE frame from the LAN Port across LAN Bridge Link number 1 to the Bridge (Figure 24). Since the frame is an All Routes Explorer, the Bridge broadcasts the frame across each of the existing WAN Bridge Links (32 max) to the WAN Adapter module.

6)The WAN Adapter transmits each ARE frame to a separate, already established SVC which connects it across the WAN to a remote node (Figure 25). Note that in the node attached to LAN AAA, three bridge links (5, 6, and 7) to the WAN side are necessary because they go to the three remote LANs to establish complete bridges to those LANs. The three right-hand nodes really need only one WAN Bridge Link each, but two additional ones are shown; they could be attached to other bridges in other nodes not shown.
