Which EIGRP term refers to the route with the lowest metric to the destination?

In Enhanced Interior Gateway Routing Protocol (EIGRP), the term that refers to the route with the lowest metric to a particular destination is the successor. A successor route is essentially the primary route that EIGRP chooses to use for forwarding packets to a destination based on the best metric available. This metric takes into account various factors, including bandwidth, delay, load, and reliability, which EIGRP uses to calculate the most efficient path.

When EIGRP processes routing information, it evaluates all possible paths to a destination and selects the path with the lowest feasible distance as the successor. This path is stored in the routing table and is used when routing decisions are made. Given that a successor represents the most optimal route, it's crucial for maintaining efficient network performance.

In contrast, reported distance refers to the metric reported by a neighbor for a particular route and is not necessarily the best option. Feasible distance is a broader term that indicates the lowest calculated metric to a destination that includes both successor and potential successor routes. The feasible successor refers to routes that can serve as backups if the primary successor route fails but does not represent the primary route itself. Therefore, the term successor is specifically aligned with the definition of the route used for forwarding packets to a destination.
