Explanation

In EIGRP, the successor is the best path to a destination and is placed in both the routing table and the topology table. A feasible successor is a backup path that satisfies the feasibility condition - its reported distance (the metric advertised by the neighbor) must be less than the feasible distance (the current best metric) of the successor route. The feasible successor is stored only in the topology table, not the routing table, and is instantly promoted to successor if the primary route fails, enabling fast convergence without a recomputation.
