Page: 32 / 96

Figure 1: Configuration Selection Sequence
1. /config/juniper.conf —Active configuration file.
2. /config/rescue.conf —Rescue configuration file. This file is created by the router
administrator.
3. /config/juniper.conf.1
—First rollback configuration.
4. /etc/config/factory.conf
—Default factory configuration file.
The factory.conf file is the initial router configuration file shipped with the system.
All configuration settings are returned to the factory default, and access to the
router is restricted to the console. For more information on setting up your router
from the factory default configuration, see the specific hardware guide for your
router.
Remote Storage of Configuration Files
Configuration files can be stored off the router. This can be helpful if the router
encounters a software failure or other problem that forces you to restore the router’s
software. Once the software is restored, you can then reload the saved configuration
file. For more information on restoring the JUNOS Software, see “Load and Commit
the Configuration File” on page 57.
When the configuration file is stored off the router, you can encrypt the configuration
files using the Data Encryption Standard (DES) encryption algorithm.
