Configuring the Router

Booting the Router for the First Time

Each time you power on the router, it goes through this boot sequence:

1.The router goes through power-on self-test diagnostics to verify basic operation of the CPU, memory, and interfaces.

2.The system bootstrap software (boot image) executes and searches for a valid Cisco IOS image (router operating system software). The source of the Cisco IOS image (Flash memory or a Trivial File Transfer Protocol [TFTP] server) is determined by the configura- tion register setting. The factory-default setting for the configura tion register is 0x2102, which indicates that the router should attempt to load a Cisco IOS image from Flash memory.

3.If after five attempts a valid Cisco IOS image is not found in Flash memory, the router reverts to boot ROM mode (which is used to install or upgrade a Cisco IOS image).

4.If a valid Cisco IOS image is found, then the router searches for a valid configuration file.

5.If a valid configuration file is not found in NVRAM, the router runs the System Configuration Dialog so you can configure it manually. For normal router operation, there must be a valid Cisco IOS image in Flash memory and a configuration file in NVRAM.

The first time you boot your router, you will need to configure the router interfaces and then save the configuration to a file in NVRAM. Proceed to the next section, Configuring the Router, for configuration instructions.

You can configure the router using one of these procedures:

Configuration mode recommended if you are familiar with Cisco IOS commands.

zAutoInstall-Recommended for automatic installation if anothe router running Cisco IOS software is installed on the network. This configuration method must be set up by someone with expe- rience using Cisco IOS software.

zSystem Configuration Dialog-Recommended if you are not famil- iar with Cisco IOS commands.

zUse the procedure that best fits the needs of your network config- uration and level of Cisco IOS experience.
