NetFlow is primarily concerned with the collection and analysis of flow information, so the location of the collector and the amount of flow information sent to it are key considerations for a network designer.

Question 2

When a router running EIGRP takes alternate paths into consideration, which ones will it consider loop-free?
A) ones in which the feasible distance is the same as the best possible route
B) ones in which the reported distance is less than the feasible distance
C) ones in which the reported distance is the same as the metric of the best possible path
D) ones in which the reported distance is equal to the feasible distance

Accepted Answer

EIGRP considers a path loop-free if the reported distance (RD) is less than the feasible distance (FD) of the current best path. This is known as the feasibility condition.
