Sure, here is an SEO-friendly HTML answer for the interview question about EIGRP feasible successor and reported distance:

What is the difference between EIGRP feasible successor and reported distance?

EIGRP (Enhanced Interior Gateway Routing Protocol) feasible successor and reported distance are important concepts in network routing. The focus keyword is EIGRP feasible successor. Let me explain the difference between the two:

• Feasible Successor: In EIGRP, a feasible successor is a backup route that is considered a valid path to a destination network. It is a route with a lower advertised distance than the current successor route, making it ready to take over in case the primary route fails. Feasible successors are stored in the topology table and can be quickly used for routing if needed.
• Reported Distance: Reported distance is the EIGRP metric value advertised by the neighboring router for a specific route. It represents the total distance from the current router to the destination network through the neighbor router. The reported distance is used by the local router to calculate the best route to the destination.

In summary, the main difference between EIGRP feasible successor and reported distance is that feasible successor is a backup route to reach a network, while reported distance is the metric value advertised by a neighboring router for that route.

Understanding these concepts is crucial for optimizing routing performance and ensuring network reliability in EIGRP-based environments.
