- Specify only if you want to override part of the OVN-Kubernetes configuration.
- The maximum transmission unit (MTU) for the Geneve (Generic Network Virtualization Encapsulation) overlay network. This is detected automatically based on the MTU of the primary network interface. You do not normally need to override the detected MTU.
If the auto-detected value is not what you expected it to be, confirm that the MTU on the primary network interface on your nodes is correct. You cannot use this option to change the MTU value of the primary network interface on the nodes.
If your cluster requires different MTU values for different nodes, you must set this value to
100less than the lowest MTU value in your cluster. For example, if some nodes in your cluster have an MTU of
9001, and some have an MTU of
1500, you must set this value to
- The UDP port for the Geneve overlay network.
