+The maximum transmission unit (MTU). If you do not set a value, the Cluster Network Operator (CNO) sets a default MTU value by calculating the difference among the underlay MTU of the primary network interface, the overlay MTU of the pod network, such as the Geneve (Generic Network Virtualization Encapsulation), and byte capacity of any enabled features, such as IPsec.
