EIGRP Tables - sure come out in exam!

•Like OSPF, EIGRP keeps this information in several tables, or databases.
–Neighbor table
–Topology table
–Routing table
–Successor
–Feasible Successor

•Successor – Current Route
–A successor is a route selected as the primary route to use to reach a destination.
–Successors are the entries kept in the routing table.

•Feasible Successor - A backup route
–A feasible successor is a backup route.
–These routes are selected at the same time the successors are identified, but they are kept in the topology table.
–Multiple feasible successors for a destination can be retained in the topology table.


Neighbor table - lists adjacent routers
Topology table - contain Feasible Successor
Routing table - contain Successor
