What must be true for a static route to be included in the route table on FortiGate devices?

For a static route to be included in the route table on FortiGate devices, it is essential that the link health monitor is successful. Link health monitoring is a feature that checks the reachability of a specific destination over the network. If the health monitor confirms that the path or interface associated with the static route is operational and reachable, the static route will be added to the routing table.

This mechanism helps ensure that traffic is only routed through interfaces that are confirmed as up and running, enhancing the reliability and stability of the network connections. If the health monitor fails, the static route associated with that link would not be used, even if other conditions for the route's validity are met. Therefore, successful link health monitoring is a critical requirement for the inclusion of a static route in the FortiGate routing table.
