Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 260

Identify three characteristics of EIGRP feasible successors? (Choose three.)

Answer options

• A. A feasible successor is selected by comparing the advertised distance of a non-successor route to the feasible distance of the best route.
• B. If the advertised distance of the non-successor route is less than the feasible distance of best route, then that route is identified as a feasible successor.
• C. If the successor becomes unavailable, then the feasible successor can be used immediately without recalculating for a lost route.
• D. The feasible successor can be found in the routing table.

Correct answer:

Explanation

Option A correctly describes the process of selecting a feasible successor based on advertised and feasible distances. Option B accurately states that a non-successor route is identified as a feasible successor when its advertised distance is lower than the feasible distance. Option C is correct because feasible successors provide a backup without recalculation if the primary successor fails. Option D is incorrect because feasible successors are not directly listed in the routing table; they are derived from the EIGRP topology table.
