Question

Fortigate Firewall 101F Interface config

I have created the BDI interfaces on the Cisco SD-WAN routers with VRRP. Fortigate firewalls are working in active passive mode. We have connections to both routers from each firewall. Please suggest the config to follow here on FortiGate so that in case the link to SD-WAN router 1 goes down from FortiGate firewall 1, traffic should go out from SD-WAN router 2 from FortiGate firewall 1 link. Please suggest other options also

Thanks for sharing the documentation.

In the snip, we connect to both routers from the active and passive firewall on the same VLAN. meaning, Physical interfaces on firewalls connecting to the router are in the same network. Is there any way, i can add fw ports in same vlan and so both ports become part of same network.
