Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 221

After DUAL calculations, a router has identified a successor route, but no routes have qualified as a feasible successor. In the event that the current successor goes down, what process will EIGRP use in the selection of a new successor?

Answer options

• A. EIGRP will find the interface with the lowest MAC address
• B. The route will transition to the active state
• C. The route will transition to the passive state

Correct answer: E, I, G, R, P

Explanation

When a successor route fails and no feasible successors are available, EIGRP will transition the route to the active state to search for a new path. The other options are incorrect because EIGRP does not use MAC addresses for route selection and the passive state does not apply in this scenario.
