Dark Fiber Backup IPSEC design programming

Looking for way to design a network that is currently dark fiber with 3 sites. Need to create a failover network using IPSEC tunnels using 3 Fortigate firewalls in case fiber goes down. Sites are currently using EIGRP and Cisco L3 Switches. I would imagine this would need to be changed to OSPF?

All clients go to Site1 for internet/server access

Site 1 (Internet/Servers/Clients) (DHCP/DNS)

Site 2 (Clients)

Site 3 (Clients)

Drawings below of current environment and proposed environment. We have more VLANS but made the drawings for simplicity purposes.

Looking for programming advise.
