Restoring a Saved Configuration

To restore a saved configuration, perform the following tasks:

Copy Saved Files to the Router

To copy the saved configuration to the router:

Log in to the console as root. There is no password:Escape character is '^]'. [Enter] router (ttyd0) login: root Password: [Enter]
Initially, access to the router is limited to the console port after a recovery installation. Access through the management ports and interfaces is set in the configuration. For information on accessing the router through the console port, see the administration guide for your particular router.
Start the CLI:# cli

Copy the remote configuration file to the router’s /var/tmp directory:



root@host> ftp remote-server

user: username

password: password

ftp> bin

Type set to I.
ftp> get /path/file

ftp> bye

Goodbye.

Once the saved configuration file is copied to the router, you load and commit the file:

Start the CLI configuration mode:



user@routername> configure

Entering configuration mode
    

[edit]

user@host#

Load the file into the current configuration. You should override the existing file:user@host# load override /var/tmp/filename load complete
Commit the file: user@host# commit commit complete
Exit the CLI configuration mode:user@host# exit user@host>
Back up the JUNOS software.
After you have installed the software on the router, committed the configuration, and are satisfied that the new configuration is successfully running, issue the request system snapshot command to back up the new software to the /altconfig file system. If you do not issue the request system snapshot command, the configuration on the alternate boot drive will be out of sync with the configuration on the primary boot drive.

The request system snapshot command causes the root file system to be backed up to /altroot, and /config to be backed up to /altconfig. The root and /config file systems are on the router’s CompactFlash card and the /altroot and /altconfig file systems are on the router’s hard disk.
