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. For the values shown, you should
instead enter values appropriate for your network.
• You should be familiar with Cisco IOS software and its conventions.
Note To use the verification steps described in this chapter, you must be familiar
with Cisco IOS 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, see the “Understanding Command Modes”
section in the “Introduction to Router Configuration” chapter.
Dial-Up ISDN Connection to a Central-Site Router
This section tells how to configure your Cisco router for Internetwork Packet
Exchange (IPX) when dialing out over an ISDN line. Configure your router for IP
if you want to use Internet services, such as the World Wide Web, or if the network
that you are dialing into uses IP. Configure your router for IPX if your network
uses IPX network services, such as NetWare file servers or print servers.
This configuration assumes that the Cisco router is dialing into a central-site
router.
Note If you are using IP but not IPX on your network, do not enter the commands
that include the ipx keyword.
These are the major tasks in configuring your router:
• Configuring Global Parameters
• Configuring Security
• Configuring the Fast Ethernet Interface
• Configuring the ISDN Interface
• Configuring Static Routes and Dialing Behavior
• Configuring Command-Line Access to the Router
