Which three statements are true regarding EIGRP? (Choose three.)

A.
To speed convergence, EIGRP attempts to maintain a successor and feasible successor path
for each destination.

B.
By default, EIGRP performs auto-summarization acrossclassful network boundaries.

C.
By default, EIGRP uses theDijkstra algorithm to determine the best path to a destination
network based on bandwidth and delay.

D.
EIGRP uses an area hierarchy to increase network scalability.

E.
EIGRP uses hellos to establish neighbor relationships.
