Configuring a Router
You can configure or modify the configuration of the router using one of the procedures described in the
following sections:
• Performing a Basic Configuration Using AutoInstall, page 4-3
• Performing a Basic Configuration Using the Setup Facility, page 4-4
• Performing a Basic Configuration Using Global Configuration Mode, page 4-7
Follow the procedure that best fits the needs of your network configuration.
Note You need to acquire the correct network addresses from your system administrator or consult your
network plan to determine correct addresses before you can complete the router configuration.
Enter the show version command to display the router model and the release of Cisco IOS software that
is supported on the router. (See the “Viewing the System Configuration” section on page 4-19 for sample
output of the show version command.)
Performing a Basic Configuration Using AutoInstall
The AutoInstall process configures the router automatically after connection to the WAN. A
Transmission Control Protocol/Internet Protocol (TCP/IP) host on your network must be preconfigured
to provide the required configuration files. The TCP/IP host may exist anywhere on the network
provided the following two conditions are met:
1. The host must be on the remote side of the router’s synchronous serial connection to the WAN.
2. User Datagram Protocol (UDP) broadcasts to and from the router and the TCP/IP host are enabled.
Do not use AutoInstall unless the required files are available on the TCP/IP host. Refer to the
publications Configuration Fundamentals Configuration Guide and Configuration Fundamentals
Command Reference for information about how AutoInstall works. (See “Related Documentation”
section on page xi for more information.
To configure the router using AutoInstall, complete the following steps:
Step 1 Attach the appropriate synchronous serial cable to an available synchronous serial interface on the
router.
Step 2 Turn the power switch on the power supply to the on (|) position. (This action supplies AC power to the
router.)
The router loads the operating system image from Flash memory. If the remote end of the WAN
connection is connected and properly configured, the AutoInstall process begins.
Step 3 After the AutoInstall process is complete, use the copy running-config startup-config command to
write the configuration data to the router’s nonvolatile random-access memory (NVRAM).
Hostname# copy running-config startup-config
Note This step saves the configuration settings to NVRAM. If you fail to do this, your configuration will be
lost the next time you reload the router.
