  • 1.  Why getting "mgd: error: configuration check-out failed Validation failed"?

    Posted 12-22-2009 13:16

    Why I was getting "mgd: error: configuration check-out failed, Validation failed" when tryiong to upgrade J2320 from 8.5R4.3 to 9.6R2.11?

     

    I have load the factory-default config to J-2320 but still getting the same error, what minimum config I need for J-2320?

     

    Would 9.6R2.11 support VPLS?

    Hello there,

    JUNOS upgrade is officially supported across 3 or less major versions at a time.

    Therefore to go from 8.5 to 9.6 you formally need to upgrade first to 9.2 maximum , then to 9.5 and then to 9.6.

    But if you could afford factory-defaulting this box , I would say do not worry, go straight to 9.6 and use "no-validate" knob.

    The worst thing you could experience is that the box becomes "Amnesiac" and you have to configure it from scratch - which is not very different from factory-default config.

    That being said, I assume you upgrade from JUNOS-ES 8.5 to JUNOS-ES 9.6. The latest Legacy-Services-JUNOS for J-series is 9.3R4.

    And VPLS is supported on J-series platform with JUNOS 9.6 with restrictions, please have a look here

    Good luck!
