  • 1.  mtu less than 1600

    The Geneve overlay requires an MTU value of 1600 bytes or greater. !

    My questions are:

    in a lab or POC environment with an MTU value of 1500 does the overlay works?

    If yes, is it supported?

    In few words I'm asking if MTU>=1600 is a must or a very best practice.

    It is must , since we don't support fragmentation. The MTU size must be large enough to support extra encapsulation overhead.
