  • 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.
