Using AutoInstall
The AutoInstall process is designed to configure the router automatically after connection
to your WAN. In order for AutoInstall to work properly, 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 as
long as the following two conditions are maintained:
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
must be enabled.
This functionality is coordinated by your system administrator at the site where the TCP/IP
host is located. You should not attempt to use AutoInstall unless the required files have been
provided on the TCP/IP host. For more information, refer to the Cisco IOS configuration
guide and command reference publications.
Take the following steps to prepare your router for the AutoInstall process:
Step 1
Attach the WAN cable to the router.
Step 2
Power ON the router.
The router will load the operating system image from Flash memory. If the
remote end of the WAN connection is connected and properly configured, the
AutoInstall process will begin.
