Campus-REX IP Addresses
Each Campus-REX unit has two IP addresses, the LAN address and the Line 
address. In the following figure, the non-shaded side of the Campus-REX 
indicates the LAN address, which is for the Ethernet (10BASE-T) 
connection. The shaded side of the Campus-REX is the IP Line address, 
which is for the HDSL connection. Note that the IP Line address is different 
from the LAN addresses. When connecting two Campus-REX units 
point-to-point through HDSL, the IP Line addresses are completely isolated 
and hidden from the rest of the network. You can assign any subnet to the 
Line IP addresses.
When routing, data travels one hop at a time. The figure below shows 
destination and next hop IP addresses. The destination address indicates the 
network and subnetwork of the next hop. The next hop is the next-stop IP 
address node. The default gateway is the upstream routing device. Use this 
example to help you determine/record static IP routing addresses.
