6. Optionally, configure a DCE clock rate for the serial line, unless

You must use a DTE interface on the new router because the network
always provides the clock signal.
In this example, the existing router's configuration file contains the
commands needed to configure the router for Frame Relay AutoInstall
on a serial line:
Router# configure terminal
interface serial 0
ip address 172.31.20.20 255.255.255.0
encapsulation frame-relay
frame-relay map ip 172.31.10.1 255.255.255.0 48
ip helper-address 172.31.20.5
Set Up the TFTP Server
For AutoInstall to work correctly, the new router must resolve its host
name and then download a name-confg or a name.cfg file from a TFTP
server. The new router can resolve its host name by using a network-
confg or a cisconet.cfg file downloaded from a TFTP server or by
using the DNS.
To set up a TFTP server to support AutoInstall, complete these tasks.
Step 2 includes two ways to resolve the new router's host name. Use
the first method if you want to us
network-confg
file to resolve the
new router's host name. Use the second method if you want to us
DNS to resolve the new router's host name.
