Obtaining the Kernel and Configuration Files
With a known IP address, an AN/ANH and ARN router can obtain its
operating-system kernel and configuration files over the network. The procedure
is the same for EZ-Install, Netboot, and Directed Netboot.

The router sends a BootP request for the path names of the startup files.
The router issues the request simultaneously through all serial (COM),
Ethernet, and token ring (ARN only) interfaces that have IP addresses. The
router issues this request periodically for approximately 3 minutes, regardless
of whether a cable is connected.
A BootP server responds to the router's request with the directory path names
(Figure 1-3).
Corporate backbone
The first router interface that processes the BootP response acts as the TFTP
client in the remaining steps.
The router stops sending BootP requests.
