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:
z
An HDLC-encapsulated serial line (the default configuration for
serial line)
z
An Ethernet, Token Ring, FDDI interface
z
A 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.
interface serial interface-number
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.
