Chapter 5: Using AutoInstall

Perform the

AutoInstall

Procedure

To dynamically configure a new router using AutoInstall, complete these tasks. Steps 1, 2, and 3 are completed by the central administra- tor. Step 4 is completed by the person at the remote site.

1.Modify the existing router's configuration to support AutoInstall.

2.Set up the TFTP server to support AutoInstall.

3.Set up the BOOTP or RARP server if needed. A BOOTP or RARP server is required for AutoInstall using an Ethernet, Token Ring, FDDI, or Frame Relay-encapsulated serial interface. With a Frame Relay-encapsulated serial interface, the existing router acts as the BOOTP server. A BOOTP or RARP server is not required for AutoInstall using an HDLC-encapsulated serial interface.

4.Connect the new router to the network.

Modify the Existing Router's Configuration

You can use any of these interfaces:

zAn HDLC-encapsulated serial line (the default configuration for serial line)

zAn Ethernet, Token Ring, FDDI interface

zA Frame Relay-encapsulated serial line

Use an HDLC-Encapsulated Serial Interface Connection

To set up AutoInstall via a serial line with HDLC encapsulation (the default), you must configure the existing router. Perform these steps, beginning in global configuration mode:

1.Configure the serial interface that connects to the new router with HDLC encapsulation (the default), and enter interface configura tion mode.

2.Enter an IP address for the interface. The host portion of the ad dress must have a value of 1 or 2. (AutoInstall over Frame Relay does not have this address constraint.

3.Configure a helper address for the serial interface to forward broadcasts associated with the TFTP, BOOTP, and DNS requests.
