Chapter 2. Planning for Router Configuration 29
Chapter 2. Planning for Router ConÞguration
This chapter describes the terminology and the information that you need to obtain before configuring the router.
The information needed to configure the router is contingent on the chosen Link Protocol. It is therefore important
to know which Link Protocol you are using (this is determined by your Network Service Provider) so that you can
refer to the configuration sections that apply to your setup.
When you configure the router using the Command Line Interface, the planning is similar to the process described
for Configuration Manager with very few exceptions.
Important Terminology
You should familiarize yourself with the following terminology as it will be used throughout this chapter.
Target router. Router that you are configuring. Also referred to as local router.
Remote routers. All the routers to which the target (local) router may connect.
Remote router database. Database which resides in the target router and contains information about the remote
routers to which the target router may connect.
Remote router entry. Entry about a remote router in the target router database. A remote router entry defines:
¥ Connection parameters
¥ Security features
¥ Route addressing and bridging functions
