Autoinstallation Process on Services Router

When the Services Router is powered on for the first time, autoinstallation attempts the following on each connected interface simultaneously:

1. The Services Router sends out DHCP, BOOTP, RARP, or SLARP requests to obtain an IP address.
2. If a DHCP server responds, the router obtains the following:
   • An IP address and subnet mask
   • The address of the Trivial File Transfer Protocol (TFTP), Hypertext Transfer Protocol (HTTP), or File Transfer Protocol (FTP) server with the configuration file
   • The IP address of the TFTP server

   Optionally, the hostname of the TFTP server is obtained from the DHCP server. Usually, the TFTP address or name is specified, not both. If the name is specified, a DNS server must be available to translate the name of the TFTP server into an IP address.

   If the TFTP server is not on the same LAN segment as the new Services Router, or if a specific router is required by the network, then the IP address of an intermediary router must be specified. This address is used as the location to receive TFTP requests for autoinstallation.
