Which default route will be active when configured with multiple routes?

When multiple default routes are configured in MikroTik, the router uses a concept called metric to determine which route should be active. The default route with the lowest metric will take precedence and be the active route used for traffic that does not match any more specific route.

In this scenario, the route via gateway 2.2.2.2 is considered the active default route, indicating that it has the lowest metric compared to the others. This means that any outbound traffic without a specific route will be sent through this gateway.

Choosing the correct gateway for default routes ensures optimal routing and load balancing as needed. The other gateways (1.1.1.1 and 3.3.3.3) may still exist in the routing table, but if they have higher metrics, they will not be used until the active route becomes unavailable. This setup allows for redundancy but prioritizes an efficient routing path based on metric values.
