4-2 Cisco Multiport Router Installation and Configuration Guide
Configuring the Router
by the configuration register setting. The factory-default setting for the configuration
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.
Configuring the Router
You can configure the router following one of the procedures:
• Using Configuration Mode—Recommended if you are familiar with Cisco IOS
commands.
• Using AutoInstall—Recommended for automatic installation if another router running
Cisco IOS is installed on the network. This configuration method must be set up by an
advanced Cisco IOS user.
• Using the Setup Facility—Recommended if you are not familiar with Cisco IOS
commands.
Proceed with the procedure that best fits the needs of your network configuration and
Cisco IOS experience level.
Note You need to obtain the correct network addresses from your system administrator or
consult your network plan to determine correct addresses before you can complete the
configuration of your multiport serial router.
