Which is true regarding EIGRP successor routes?
1.A successor route is used by EIGRP to forward traffic to a destination.
2.Successor routes are saved in the topology table to be used if the primary route fails.
3.Successor routes are flagged as "active" in the routing table.
4.A successor route may be backed up by a feasible successor route.
5.Successor routes are stored in the neighbor table following the discovery process.
Answer: C
Successor routes are the routes picked from the topology table as the best route to a remote network, so these are the routes that IP uses in the routing table to forward traffic to a remote destination. The topology table contains any route that is not as good as the successor route and is considered a feasible successor, or backup route. Remember that all routes are in the topology table, even successor routes.
