5. Save the configuration file to your startup configuration. This step
saves the configuration to NVRAM.

Typically, the local-area network (LAN) interface and IP address ar
already configured on the existing r outer. You might need to configur
an IP helper address if the TFTP server is not o n the same network as
the new router.
In this example, the existing router's configuration file contains the
commands needed to configure the router for AutoInstall on an Ether-
net interface:
Router# configure terminal
interface Ethernet 0
ip address 172.31.10.1 255.255.255.0
ip helper-address 172.31.20.5
Ctrl-Z
Router(config)# copy running-config start up-c onfig
Use a Frame Relay-Encapsulated Serial Interface Connection
To set up AutoInstall via a serial line wit h Frame R elay e ncapsul ation,
you must configure the existing router. Perform these tasks, beginning
in global configuration mode:
1. Configure the serial interfa ce that connects to the new router, and
enter interface configuration mode.
interface serial 0
2. Configure Frame Relay encapsulation on the interface that con-
nects to the new router.
encapsulation frame-relay
3. Create a Frame Relay map pointing back to the new router, or
point-to-point subinterfaces, assign a data link connection identi-
fier (DLCI) to the interface that connects to the new router, and
provide the IP address of the serial port on the new router.
frame-relay map ip
ip-address dlci
