What should be the ideal MTU size for docker bridge on a openstack VM?


As OpenStack uses VXLAN tunnels for communication. VXLAN tunnel has 50 bytes reserved for the headers. Suppose host machine NIC has MTU of 1500 then OpenStack VMs will have MTU of 1450. So ideally docker bridge should have MTU size <= 1450.
