Configuring Remote Access
1-10 114084 Rev. A
If both serial interfaces receive BOOTP responses, the AN/ANH/ARN
assigns the respective IP addresses to each interface.
Getting Kernel Image and Configuration Files
With a known IP address, the AN/ANH/ARN can get image and configuration
files.
1. The AN/ANH/ARN sends a BOOTP request for the pathnames of a
configuration file and image kernel.
The router issues the request simultaneously through all serial (COM),
Ethernet, and Token Ring (ARN only) interfaces that have IP addresses. It
issues this request periodically for about 3 minutes, regardless of whether a
cable is connected.
2. A BOOTP server responds to the router’s request with the directory
pathnames (F
igure 1-3).
Figure 1-3. Getting the Pathnames of the Kernel and Configuration Files
The first router interface that processes the BOOTP response acts as the TFTP
client in the remaining steps.
