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 a 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. 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.
