Router Configuration
You can perform a basic configuration for your router by using either the
setup
command automatic prompt method, or the global configuration method in which
you enter each option and parameter manually. Configuration is described in these
sections:
•
Before You Begin, page 3-49
•
setup Command, page 3-49
•
Global Configuration Mode, page 3-50
Before You Begin
Before you begin the configuration process for your router, you should have the
following information available:
•
Interfaces the router will use
•
Routing protocols the router will support
•
Network addresses for the protocols being configured
•
Password scheme for your environment
setup Command
One option is to use the
setup
command, also known as the
setup
command
utility. During the first startup of an unconfigured router, the system automatically
starts the
setup
command utility, which enables you to begin configuring your
router. The
setup
command utility presents a structured, interactive script that
guides you through the process.
You can invoke the
setup
command utility at any time by issuing the
setup
command at the privileged EXEC mode prompt (
Router#
), which invokes the
same configuration script that appears automatically during the first startup of an
unconfigured router. You can enter the
setup
command at any time to alter
previously entered configuration information.
The advantage in using the
setup
command utility is that the system uses an
interactive script to guide you through the configuration process.
