SD-WAN overlay templates
Most SD-WAN deployments require complex overlay configurations for datacenter or cloud connectivity. The SD-WAN overlay template includes a wizard to automate and simplify the process using Fortinet's recommended IPsec and BGP templates.
Note that the overlay template does not provide any SD-WAN intelligence. Please configure an SD-WAN template to complete the SD-WAN configuration. The overlay template also assumes connectivity between the HUB and branch in order to build the overlay tunnels. This can be accomplished in a variety of ways, such as static routes, dynamic routing protocol (BGP) or through a DHCP provided static route.
When the SD-WAN overlay template has been configured, it generates the necessary IPsec, BGP and CLI provisioning templates that are required for the creation of your SD-WAN overlays. These provisioning templates are automatically assigned to the SD-WAN branch and hub devices identified in the template's wizard. Provisioning templates created by the SD-WAN overlay template are also automatically organized into template groups for each hub and branch configuration. See Template groups.
To deploy the SD-WAN overlays in your environment, you can install the branch and hub provisioning templates to your devices using the FortiManager Device Manager. See Using the SD-WAN overlay template.
By default, the branch_id metadata variable is created by the template and each SD-WAN branch device must be configured with a unique branch ID value. When Automatic Branch ID Assignment setting is enabled in the wizard, the branch ID is automatically applied to devices in the branch device group. See Automatic Branch ID Assignment.
Additional meta variables can be created for use in the template's text fields to further improve deployment scalability. See ADOM-level metadata variables.
You can configure a new SD-WAN Overlay Template by going to Device Manager > Provisioning Templates > SD-WAN Overlay Templates.
