To install software upgrades on a router with limited storage space, using the CLI:
Replace path with the full path name to the bundle. Replace release with the software release version of the bundle. Customers in the United States and Canada use the release-domestic.tgz bundle. All other customers use the release-export.tgz bundle.
All the software is activated when you issue the reboot command.
The router then reboots from the primary boot device on which you just installed the software. When the reboot is complete, the router displays the login prompt.
