When editing an exising SD-WAN overlay template, the provisioning templates that were generated by the SD-WAN overlay template previously are updated. These updated provisioning templates can then be reinstalled to applicable SD-WAN branch and hub devices.
You can also directly edit the provisioning templates generated by the SD-WAN overlay template (for example, BGP and IPsec templates), but further edits to the SD-WAN overlay template may overwrite those changes. For example, you can change the Local AS setting in the BGP hub template, but when the SD-WAN overlay template is run again, the field is updated with the value specified by the SD-WAN overlay template. Fields not included by the SD-WAN overlay template, such as descriptions, are not affected.
- Go to Device Manager > Provisioning Templates > SD-WAN Overlay Templates.
- Select a template from the list, and click Edit in the toolbar.
- Edit the template details by following the wizard, and click Finish to save your changes.
Previously generated provisioning templates are updated to match the newly configured settings, and can be installed to devices.
