space on the compact flash to perform an upgrade that keeps a copy of the
package on the router.
3. After the software package is installed, reboot the router:
user@host> request system reboot
When the reboot is complete, the router displays the login prompt.
Installing Software Upgrades from a Remote Server
To install the software upgrades from a remote server:
1. Install the JUNOS software with enhanced services package on the Services
Router, entering the following command in operational mode in the CLI:
user@host> request system software add validate unlink no-copy source
Replace source with one of the following paths:
■
ftp://hostname/pathname/package-name
or
■
http://hostname/pathname/package-name
By default, the request system software add command uses the validate option
to validate the software package against the current configuration as a prerequisite
to adding the software package. This validation ensures that the router can reboot
successfully after the software package is installed. This is the default behavior
when you are adding a software package.
The unlink option removes the package at the earliest opportunity so that the
router has enough room to complete the installation.
(Optional) The no-copy option specifies that a software package is installed, but
a copy of the package is not saved. Include this option if you do not have enough
space on the compact flash to perform an upgrade that keeps a copy of the
package on the router.
2. After the software package is installed, reboot the router:
user@host> request system reboot
When the reboot is complete, the router displays the login prompt.
