Configuring a Leased Line
The conﬁguration in this chapter describes how to conﬁgure a Cisco 1700 router for IP and IPX over
a synchronous serial line.
Before You Begin
The conﬁguration in this chapter is based on the following assumptions:
Your Cisco 1700 router hardware is correctly installed according to the Cisco 1700 Router
Hardware Installation Guide that came with the router.
Your Cisco 1700 router is using multilink Point-to-Point Protocol (PPP).
Your Cisco 1700 router is using dynamic IP and IPX routing, in which IP Routing Information
Protocol (RIP) resolves IP routes, and IPX RIP and IPX SAP dynamically resolve IPX routes and
Before you begin conﬁguration, be aware of the following:
You need to enter the commands in the order shown in the task tables.
The values shown in italic are examples. You should substitute the values shown with values that
are appropriate for your network.
You should be familiar with Cisco IOS software and its conventions.
commands and command modes. When you use the veriﬁcation steps, you need to change to
different command modes. If you are not familiar with command modes, refer to the "Understanding
Command Modes" section in the "Cisco IOS Basic Skills" chapter.
These are the major tasks when conﬁguring the router:
Conﬁguring Global Parameters
Conﬁguring the Fast Ethernet Interface
Conﬁguring the Serial Interface
Conﬁguring Dynamic Routing Parameters
Conﬁguring Command-Line Access to the Router
To use the veriﬁcation steps described in this chapter, you must be familiar with Cisco IOS
