RIDGING WITH THE
RAS 1500
Overview
The SuperStack II Remote Access System (RAS) 1500 uses bridging to
allow you to link two separate locations as if they were the same
network.
How the RAS 1500
Acts as a Bridge
When the RAS 1500 receives a frame, it inspects the frame and
determines where the frame belongs by analyzing address information.
When to Use Bridging
When a frame arrives at a bridge, the bridge analyzes the frame for the
hardware address. Figure 12 shows an example of the RAS 1500 bridge
configuration.
