You can use SD-WAN templates to configure SD-WAN for one or more devices. When you assign SD-WAN templates to a device, you are using SD-WAN central management.
If you want to use SD-WAN per-device management, do not assign SD-WAN templates to devices, and see Device DB - System SD-WAN.
SD-WAN templates help you do the following:
- Deploy a single SD-WAN template from FortiManager across multiple FortiGate devices.
- Perform a zero-touch deployment without manual configuration locally at the FortiGate devices.
- Roll out a uniform SD-WAN configuration across your network.
- Eliminate errors in SD-WAN configuration across multiple FortiGate devices since the SD-WAN template is applied centrally from FortiManager.
- Monitor network Performance SLA across multiple FortiGate devices centrally from FortiManager.
- Monitor the performance of your SD-WAN with multiple views.
Using SD-WAN templates consists of the following steps:
- Create an SD-WAN template. See SD-WAN templates.
- Assign the SD-WAN templates to FortiGate devices and device groups. See Assign SD-WAN templates to devices and device groups.
- Install device settings using the Install Wizard. See Install device settings only.
Templates should be executed in the following order:
- Interface template
- IPsec template
- SD-WAN template
- Go to SD-WAN > Monitor to monitor the FortiGate devices. See SD-WAN Monitor .
The SD-WAN template takes effect on the FortiGate device only after it is installed using the Install Wizard. After installing the SD-WAN template on the FortiGate device, changing settings in SD-WAN, Performance SLA, or SD-WAN Rules locally on the FortiGate device will result in the SD-WAN template on the FortiManager being out of sync with the FortiGate device. You must configure the same settings on the FortiManager SD-WAN template, and install it again by using the Install Wizard to be in sync with the settings on the FortiGate.
Some FortiGate model devices include a default policy to allow initial management access to the device using a specified interface.
As SD-WAN members may not use interfaces that are referenced directly in firewall policies, you must remove this reference by deleting the policy before installing the SD-WAN template.
This can be done manually through the CLI or GUI, or by installing a new policy package to the device that does not contain the default policy.
