Chapter 8 - Internetworking and Management Overview
Configure a Static Route entry in any of the external routers that may have been specified as a Default Router IP address or as a Gateway address in the Campus-REX2. You may also configure the Campus-REX2 to send periodic route updates using Routing Information Protocol (RIP) so that other external routers can automatically update their routing tables. This implementation prevents other parties from eavesdropping to discover routes to remote sites connected through the HDSL line. The format of this entry varies among different router vendors, but it will typically be in the form of Destination, Mask, and Next Hop Gateway, where:
•destination is the remote IP subnet or host address
•gateway is the LAN IP address of the Campus-REX2 on the same subnet as the external router
The following figure shows an example of a point-to-point HDSL system with hypothetical parameter values.
