In the main menu of the Open Single Management Platform Console, go to the Application & Services → NGFW → Devices or Network templates → <name of the device or network template> section and select the Routing → Static routes tab.
A table of static routes is displayed.
If you navigated to the Static routes section through Application & Services → NGFW → Devices and want to configure static routes locally on the device, enable the Override toggle switch and confirm the action. Static routes on the device will not be synchronized with the template, and you can add or edit static routes locally.
If this switch is disabled, the device uses the static routes configured in the template that is applied to the device, and local editing of static routes in this section is not possible. By default, this toggle switch is enabled.
Select the check box next to one or more static routes that you want to delete.
In the upper part of the table, click the Delete button and confirm the action.
Apply the OSMP policy changes by clicking the Commit and push button.
One or more selected static routes are deleted from the device or template.
