AutoInstall Requirements

The AutoInstall process is designed to configure the router automati- cally 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 net- work as long as these two conditions are maintained:

zThe host must be on the remote side of the router's synchronous serial connection to the WAN.

zUser 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.

Note:	AutoInstall works on synchronous serial connections
	only. The 2-wire switched 56-kbps DSU/CSU module op
	erates on switched 56-kbps circuits only; therefore, you
	cannot use it for AutoInstall.

In addition, your system must meet these requirements:

zRouters must be physically attached to the network using one o more of the following interface types: Ethernet, Token Ring, Fiber Distributed Data Interface (FDDI), serial with High-Level Dat Link Control (HDLC) encapsulation, or serial with Frame Relay encapsulation. HDLC is the default serial encapsulation. If the Au- toInstall process fails over HDLC, the Cisco IOS software auto- matically configures Frame Relay encapsulation.

Note:	For Token Ring interfaces, only those that set ring speed
	with physical jumpers support AutoInstall. AutoInstall
	does not work with Token Ring interfaces for which the
	ring speed must be set with software configuration
	commands. If the ring speed is not set, the interface is set
	to shutdown mode.

zYou must complete Step 1 and either Step 2 or 3:

1.A configuration file for the new router must reside on a TFTP server. This file can contain the minimum or full configuration needed for the administrator to Telnet into the new router for con- figuration. In addition, make sure to complete one of the next two procedures:

2.A file named network-confg also must reside on the server. The file must have an Internet Protocol (IP) host name entry for the new router. The server must be reachable from the existing router.
