Explanation

The Multi-Exit Discriminator (MED) is a BGP attribute used to influence the preferred path for incoming traffic from an external autonomous system (AS). The diagram shows that FortiGate_1 advertises MED 200, while FortiGate_2 advertises MED 300, meaning the ISP will prefer the route through FortiGate_1 because a lower MED is preferred in BGP. To modify the MED value on FortiGate_1 for routes advertised to AS 30, the administrator must configure a route-map-out. A route map can match specific routes and set the MED value before sending them to the BGP neighbor.
