Installing Software Upgrades with the CLI

To install software upgrades on a router with the CLI:

1. Download the software package as described in Downloading Software Upgrades from Juniper Networks.
2. Copy the software package to the router. We recommend that you copy it to the /var/tmp directory.
3. Install the new package on the Internet Router:
   user@host> request system software add no-validate unlink reboot source

   Replace source with one of the following paths:

   • For a software package that is installed from a local directory on the router—/pathname/package-name
   • For software packages that are downloaded and installed from a remote location:
     • ftp://hostname/pathname/package-name
     • http://hostname/pathname/package-name

   The no-validate option bypasses the validation of the software package against the current configuration as a prerequisite to adding the software package.

   The unlink option removes the package at the earliest opportunity so that the router has enough room to complete the installation.

   Adding the reboot command reboots the router after the upgrade is validated and installed. Rebooting takes place only if the upgrade is successful.

   When the reboot is complete, the router displays the login prompt.
