Selecting The Routine Startup Option; Recommendations; Netboot - Nortel Remote Access for AN and Passport ARN Routers Configuration Manual

Configuring Remote Access for AN and Passport ARN Routers
The Quick-Start procedure initially tailors the default configuration file; use
Site Manager to complete the configuration. See Appendix C for more
information.

Selecting the Routine Startup Option

This section provides information to help you select the boot configuration for
routine startup operations.

Recommendations

Nortel Networks recommends that you do the following:
• Maintain the complete software image file (an.exe or arn.exe) on the local file
system at all times, in case the network connection to the BootP server goes
down and the router needs to use Local Boot for startup.
• Set up the network to support Netboot even if you plan to use the Local Boot
option. With the network set up to support Netboot, you can boot the router
over the network for some procedures and boot it locally for others.

Netboot

Netboot takes longer than the other startup options, but has many benefits.
Note: Over a low-speed WAN, or after configuring AN/ANH and ARN
routers to run several protocols, netbooting can take up to 15 minutes. It takes
less time to netboot only the kernel file or configuration file.
Using Netboot for routine startups allows you to:
• Manage software image and configuration files from a remote location by
storing them on the BootP server
This option greatly simplifies the management of remote routers by allowing
you to keep the startup files up-to-date in a single location -- the BootP server.
