on the new router makes three unicast TFTP requests for hostname.conf. If these
attempts fail, the router broadcasts three requests to any available TFTP server
for the file.
c. If the new router cannot locate hostname.conf, the autoinstallation process unicasts
or broadcasts TFTP requests for a default router configuration file called
network.conf, which contains hostname-to-IP address mapping information, to
attempt to find its hostname.
d. If network.conf contains no hostname entry for the new router, the autoinstallation
process sends out a DNS request and attempts to resolve the new router’s IP
address to a hostname.
e. If the new router can determine its hostname, it sends a TFTP request for the
hostname.conf file.
f. If the new router is unable to map its IP address to a hostname, it sends TFTP
requests for the default configuration file router.conf.
3. After the new router locates a configuration file on a TFTP server, autoinstallation
downloads the file, installs the file on the router, and commits the configuration.

Before You Begin Autoinstallation on an ACX Series Universal Access Router
To configure a router for autoinstallation, complete the following tasks:
•
Make sure you have a DHCP server on your network to meet your network requirements.
•
Create one of the following configuration files and store it on an HTTP, FTP, or TFTP
server in the network:
•
A host-specific file with the name hostname.conf for each router undergoing
autoinstallation. Replace hostname with the name of a router. The hostname.conf
file typically contains all the configuration information necessary for the router with
this hostname.
•
A default configuration file named router.conf with the minimum configuration
necessary to enable you to telnet into the new router for further configuration.
