      What does MTU mean in Ethernet?
      They are support structure for the Ethernet protocol itself. The MTU applies to the payload -- it is the largest unit of data you can cram into the packet. Thus an ethernet packet with an MTU of 1500 bytes will actually be a 1522 byte frame, and 1542 bytes on the wire (assuming there's a vLAN tag).

      How many byte is MTU?
      According to the table here, it says that MTU = 1500 bytes and that the payload part is 1500 - 42 bytes or 1458 bytes (<- this is actually wrong!). Now on top of that you have to add IPv4 and UDP headers, which are 28 bytes (20 IP + 8 UDP). That leaves my maximum possible application message to as 1430 bytes!

      Is MTU 1508 enough?
      the advise is to chose from the technical requirements taking into account the specific hardware you have. So MTU=1508 is sufficent in case you have MPLS VPN and no other feature increasing the label stack. MTU=1524 allows for 6 labels, plenty from nowadays perspective.

      Is MTU=1508 enough?
      So MTU=1508 is sufficent in case you have MPLS VPN and no other feature increasing the label stack. MTU=1524 allows for 6 labels, plenty from nowadays perspective. However it will not allow you to use EoMPLS with full sized customer frames, which requires 1526 byte as described earlier.
