An EIGRP router loses the route to a network. Its topology table contains two feasible successors to the same network. What action will the router take?

An EIGRP router loses the route to a network. Its topology table contains two feasible successors to the same network. What action will the router take?

• The DUAL algorithm is recomputed to find an alternate route.
• The best alternative backup route is immediately inserted into the routing table.
• The router will query neighbors for an alternate route.
• The router uses the default route.

Explanation: Because EIGRP uses the DUAL algorithm, the router is able to maintain information on all potential loop-free backup routes. In the event of the failure of a routing table entry, the router immediately inserts the best backup route into the routing table.
