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.

•
EZ-Install
