Configuring the CiscouBR10012Router Using AutoInstall
The AutoInstall process is designed to configure the CiscouBR10012router automatically after
connection to your WAN.
For AutoInstall to work properly, a TCP/IP host on your network must be preconfigured to provide the
required configuration files. The TCP/IP host can exist anywhere on the network as long as the following
conditions are maintained:
•The host must be on the LAN or WAN side of the router’s line card connection to theWAN.
•The User Datagram Protocol (UDP) broadcasts to and from the router.
•The TCP/IP host is enabled.
This functionality is coordinated by your system administrator at the site where the TCP/IP host is
located. You should not use AutoInstall unless the required files are available on the TCP/IP host. Refer
to the following publications for more information about AutoInstall:

Preparing for the AutoInstall Process

Complete the following steps to prepare your CiscouBR10012router for the AutoInstall process:
Step1 Attach the appropriate synchronous serial cable to the synchronous serial interface0 on the router.
Step2 Turn the power switch on each power supply to the ON (|) position. This action turns on power to the
router.
The router loads the operating system image from Flash memory; this process can take several minutes.
If the remote end of the WAN connection is connected and properly configured, the AutoInstall process
begins.
Step3 When the AutoInstall process is completed, use the copy running-config startup-config command to
write the configuration data to the router’s nonvolatile random-access memory (NVRAM):
Router# copy running-config startup-config
Completing this step saves the configuration settings that the AutoInstall process created to NVRAM. If
you fail to do this, your configuration will be lost the next time you reload the router.
