Which type of EIGRP route entry describes a feasible successor?
Click on the arrows to vote for the correct answerA. B. C. D.
EIGRP (Enhanced Interior Gateway Routing Protocol) is a distance-vector routing protocol that is used to share routing information between routers within a network. EIGRP maintains a topology table and a routing table to manage routing information.
In EIGRP, a feasible successor is a backup route to a destination network that can be used in case the primary route fails. A feasible successor is a route that meets certain conditions, including having a lower metric than the current successor route, and being loop-free. If the current successor route fails, EIGRP will automatically use the feasible successor route as the new successor route, without waiting for the routing protocol to converge.
The answer to the question is C. a backup route, stored in the topology table. Feasible successors are stored in the topology table, which maintains a list of all available routes, including successor routes and feasible successor routes. The routing table, on the other hand, only stores the best or most preferred route to a destination network.
Option A, a primary router, stored in the topology table, is incorrect because a primary router is the current best route to a destination network, not a feasible successor.
Option B, a backup router, stored in the routing table, is incorrect because backup routers are not used in EIGRP.
Option D, a primary router, stored in the routing table, is incorrect because the routing table only stores the best route, not feasible successors.
