mtu less than 1600

[vmb01]

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.
