While the software is being upgraded, the Routing Engine on which you are
performing the installation does not route traffic.
6. Log in and issue the show version command to verify the version of the software
installed.
7. (Optional) Add the jweb package using the request system software add command.
Before you can add this package, you must first download the software as you
did the installation package. For more information on downloading the
jweb
package, see “Downloading Software” on page 30.
The jweb installation module adds a router management graphical user interface
that you can use to view and configure your router. For more information about
the
jweb package, see “Installation Modules” on page 7.
8.
Transfer routing control back to the master Routing Engine:
user@host> request chassis routing-engine master switch
For more information about the
request chassis routing-engine master
command,
see the JUNOS System Basics and Services Command Reference .
9.
Verify the master Routing Engine (slot 0) is indeed the master Routing Engine:
user@host> show chassis routing-engine
Routing Engine status:
Slot 0:
Current state Master
Election priority Master (default)
outing Engine status:
Slot 1:
Current state Backup
Election priority Backup (default)
Finalizing the Installation
Once the software is installed on both Routing Engines, you return the router back
to its original configuration and back up the new installation.
1.
Restore the configuration that existed before you deleted it at the start of this
procedure:
{backup}
user@host-re0> configure
[edit]
user@host-re0# rollback 1
2.
Save the configuration change on both Routing Engines:
[edit]
user@host-re0>
commit synchronize and-quit
3.
After you have installed the new software and are satisfied that it is successfully
running, issue the
request system snapshot command to back up the new software
on both master and backup Routing Engines:
{master}
