第2章 Understanding networking settings

Procedure

1. To create your ovn.yaml file, run the following command:

   $ sudo cp /etc/microshift/ovn.yaml.default /etc/microshift/ovn.yaml

2. To list the contents of the configuration file you created, run the following command:

   $ cat /etc/microshift/ovn.yaml

   Example YAML file with default maximum transmission unit (MTU) value

   mtu: 1400

3. To customize your configuration, you can change the MTU value. The table that follows provides details:

   If you change the mtu configuration value in the ovn.yaml file, you must restart the host that Red Hat build of MicroShift is running on to apply the updated setting.

   Example custom ovn.yaml configuration file

   mtu: 1300
