feasible successor.

An EIGRP neighbor that is advertising a loop-free route to a given destination.

FEC. Forwarding Equivalence Class.

floating static.

A static route configured with a high administrative distance so that it is used only when all other paths to the destination are lost.

Forwarding Equivalence Class.
