Defining the Project Template

Typically, the following steps must be completed in order to define your Project Template:

1. Define the following aggregate subnet for your project:

   Parameter	Description
   lo_summary	A subnet summarizing all the SD-WAN device loopbacks in the project

2. If necessary, configure desired design variations (such as, Dynamic BGP, Inter-Regional ADVPN, and so on). You can also start with the default settings.
3. Define the regions of the project. For each region, define the following parameters:

   Parameter	Description
   as	Autonomous System number for the region
   lan_summary	A subnet summarizing all the corporate (internal) prefixes in the region
   lo_summary	A subnet summarizing all the SD-WAN device loopbacks in the region
   hubs	List of the Hubs serving the region

4. Define the device profiles for the project. Each profile must list the interfaces and describe their roles and settings. Define the following parameters for each interface:

   Parameter	Description
   name	Interface name, as it appears on the FortiGate device
   role	Interface role (such as LAN-facing or WAN-facing)
   ol_type	Overlay to be established over this interface
   ip	IP address (including mask) or dhcp keyword for DHCP client

5. Define the Hubs serving the project. All the Hubs referenced in the regions definition must be described here. For each Hub, define the following parameters:

   Parameter	Description
   lo_bgp	Hub loopback IP, used for BGP termination
   overlays	Dictionary describing the overlays served by this Hub

   All the overlays referenced in the device profiles using ol_type parameter must be described here. For each overlay, define the following parameters:

   Parameter	Description
   wan_ip	Hub underlay IP used to build this overlay
   network_id	Network ID used to connect to this overlay

   This overlay information will be used by the Edge devices to establish IPsec tunnels to the Hubs.

   It is a good idea to start from one of the Project Template examples provided in our GitHub repository.
