Fortigate Automation for OSPF and VPN Tunnels

Hi all,

I am looking for some guidance with setting up an automation with Fortigate. My goal is to create a stitch trigger that, when OSPF neighbor goes down, the action would be to disable the VPN Hub tunnel using a script that points to that tunnel. Then, when OSPF neighbor goes up, the action would be to enable the VPN Hub tunnel using a script again.

Unfortunately, I have not yet been able to trigger count this as I tried shutting the interface down and up.

Would anyone have an example of using OSPF to have neighbor status changed and which filter you used to do this? I think I have the action correct but not the trigger.
