Which EIGRP condition indicates that a route is feasible?

In Enhanced Interior Gateway Routing Protocol (EIGRP), a feasible route is determined by evaluating the relationship between the reported distance (the distance to a route as reported by a neighboring router) and the feasible distance (the best known distance to a route from the local router). For a route to be considered feasible, the reported distance must be lower than the feasible distance. This condition ensures that the route can be utilized without creating a routing loop, as it indicates that the path through the neighbor offers a valid alternative to the currently known best path.

Considering the other choices, a successor route is one that is actively used for forwarding traffic, but it doesn't directly relate to the condition that defines feasibility. Advertising a route by a neighboring router is only part of the overall process and does not inherently indicate that the route is feasible. Lastly, meeting load-balancing criteria pertains to the capability of using multiple paths, but it does not directly speak to the concept of feasibility in EIGRP. Thus, the correct understanding hinges on the important comparison between the reported and feasible distances to determine if a route is feasible.
