Description
Display the hostname and version information about the software running on the router or switch.
Beginning in Junos OS Release 13.3, the show version command output
includes the Junos field that displays the Junos OS version running
on the device. This field provides a consistent means of identifying the Junos OS
version, rather than extracting that information from the list of installed
sub-packages.

Additional Information
By default, when you issue the show version command on a TX Matrix
or TX Matrix Plus primary Routing Engine, the command is broadcast to all the T640
(in a routing matrix based on a TX Matrix router) or T1600 or T4000 (in a routing
matrix based on a TX Matrix Plus router) primary Routing Engines connected to it.
Likewise, if you issue the same command on the TX Matrix or TX Matrix Plus backup
Routing Engine, the command is broadcast to all the T640 (in a routing matrix based
on a TX Matrix router) or T1600 or T4000 (in a routing matrix based on a TX Matrix
Plus router) backup Routing Engines that are connected to it.

Sample Output
show version (Devices Running Junos OS Release 13.3 and Later)
The following output is from the MX240 Router and shows the
Junos field introduced in Junos OS 13.3. Depending on the
platform running Junos OS 13.3, you might see different installed sub-packages,
but the Junos field is common across all platforms that run
Junos OS 13.3 and later.
