MTU of the underlying physical network. Neutron uses this value to
calculate MTU for all virtual network components. For flat and
VLAN networks, neutron uses this value without modification. For
overlay networks such as VXLAN, neutron automatically subtracts
overlay networks such as Geneve, neutron automatically subtracts
the overlay protocol overhead from this value.
