Configuring Remote Access for AN and Passport ARN Routers

A TFTP server that contains the kernel file (krnl_arn.exe for the ARN or krnl_an.exe for the AN/ANH) or a network configuration file customized for the AN/ANH or ARN router

Compared with Netboot, Directed Netboot offers the following advantages:

Creates less network traffic

Is generally faster

Directed Netboot is usually reserved for starting AN/ANH and ARN routers after the initial startup because you need to know the exact location of the startup files. During Directed Netboot, AN/ANH and ARN routers transfer files from a TFTP server directly, bypassing negotiation with a BootP server for the IP address and path names of the startup files.

Local Boot

Local-booting the startup files for routine startups allows you to:

Minimize the time it takes the router to boot

In most configurations, however, the difference between the two options is only a few seconds. Typically, local-booting takes two to three minutes.

Minimize line usage

Obtaining files locally prevents an increase in network traffic during the startup process.

When you choose the Local Boot option for routine startups, AN/ANH and ARN routers read the IP addresses from the local configuration file and assign them to the appropriate interfaces.
