Caution: If your extended LAN includes protocol-specific routers,
make sure the total number of routers in the extended
LAN does not exceed the maximum allowed by the
protocol for a single LAN.
AUI and Backplane Connections
When the bridging connections are made through the AUI port on the
front of the Bridge Module and over the backplane, the distance between
two end-node devices can be:
8000 meters for baseband (4000 meters from the backplane
connection and 400 meters from the AUI connection)
8000 meters for broadband (4000 meters on each side of the bridge)
An example of a thick-cable configuration is shown in Figure 1-3.
