F.
Configuring unicast neighbors
Explanation:
Summarization in EIGRP also solves a problem unique to EIGRP: query scoping. EIGRP queries
do not stop until they come to a dead-end; because of this, they can loop. Route convergence
cannot proceed until all replies have been received. Summarization limits queries by stating: “only
these routes are found past this point.” Summarizing at logical points in the network is important to
prevent stuck in active (SIA)
