Understanding EIGRP Feasible Successor and Its Impact on Network Convergence

In EIGRP (Enhanced Interior Gateway Routing Protocol), a feasible successor is a backup route stored in the routing table when a primary route fails. This backup route meets the feasibility condition, meaning it has a lower advertised distance than the current successor route.

The concept of feasible successor in EIGRP plays a crucial role in improving network convergence. When a link failure occurs in the network, EIGRP can quickly switch to the feasible successor route without performing the lengthy process of re-computing the entire network topology. This results in faster convergence times and minimized network downtime.

By utilizing feasible successors, EIGRP can provide faster route recovery and improved network stability, ensuring smooth and efficient data packet delivery in the event of network disruptions.
