Selecting the Boot Configuration

Local Boot
When you choose the Local Boot option for routine startups, the router reads the
IP addresses from the local configuration file and assigns them to the appropriate
interfaces.
Local-booting the software image and/or configuration file for routine startups
allows you to
• Minimize the time it takes to boot routers.
Typically, local-booting an image takes 2 to 3 minutes. Netbooting an image
takes a little longer. For example, over a low-speed WAN or after configuring
the router to run numerous protocols, Netbooting an image can take up to 15
or 20 minutes.
It also takes less time to local-boot a configuration file than it does to Netboot
one. In most configurations, however, the difference between the two options
is only a few seconds.
• Minimize line usage.
Getting files from a BOOTP server during Netboot adds traffic to your
network during the booting process.
Recommendations
Bay Networks recommends that you
• Set up the network to support Netboot, even if you plan to use the Local Boot
option for the initial configuration and for subsequent restarts.
• Maintain the software image (an.exe) on the local file system at all times, in
case you want to use Local Boot for either of these routers.
