The EdgeRouter uses three configurations:
• Working When you make changes to the working
configuration, they are not applied until you commit the
changes to the active configuration.
• Active When you commit changes to the active
configuration, they are applied; however, the changes
do not become part of the boot configuration until you
save the changes to the boot configuration.
Boot
• When the EdgeRouter reboots, it loads the boot
configuration for use.
The following scenarios cover some of the most
commonly used commands:
• Configure an Interface (see below)
• "Remove the Default User Account" on page 41
• "Create a Firewall Rule" on page 41
• "Manage the Configuration File" on page 44
