CCNP - EIGRP Tables

Basics

 * Topology table lists every route EIGRP has learned.
 * Successor and Feasible Successor routes are taken from this table.

Successor and Feasible Successor

 * 1) Feasible and Reported Distance calculated.
 * 2) Feasible Distance = Cost to reach route.
 * 3) Reported Distnace = Cost to reach route advertised from another router.
 * 4) Route with smallest Feasible Distance chosen as Successor (forwards traffic).
 * 5) Route with smallest Reported Distance that meets the Feasible Successor Condition chosen as Feasible Successor.
 * 6) Feasible Successor condition: the route's reported distance must be smaller than the feasible distance.
