Cascade Interfaces Behavior:

When all SD-WAN members are dead, FortiGate:
✅ Shuts down the alert interface (port5) to force traffic rerouting (e.g., to a 5G backup).
❌ Does not just send alerts (Option B is incorrect).

When at least one member is alive, FortiGate: Brings port5 back up.

Be careful, all of the members in the borth of the health checks should go down to bring the port5 down.
