[j-nsp] How to pick JUNOS Version

[Alexandre Guimaraes]

The best answer ever!

Go to Vegas, in a Cassino, play some roulette.  Wait for a number between 10 and 20, if black, normal Junos, if red, SR Junos...  if you lose all money before get a code similar a release, follow Tom Beecher schemas.

IT'S A LOTTERY to pick a junos release..... 

One of my case
I have deployed some QFX5120 32C and 48Y units a year ago, exactly Aug/2019, until today, those units are offline and waiting a code that’s fix RSVP/ISIS/MPLS signalization.... until there, wasted money, etc....

    Start with the highest code version supported on the hardware that has all
    the features you need.
    Subtract 2 from the major revision number.
    Pick a .3 version of that major revision.
    Work towards current from there depending on test results, security needs,
    etc.
