A city clerk notices that a path with higher raw interface bandwidth loses to another path with a lower EIGRP composite metric. Which explanation best matches EIGRP best-path selection?
Select an answer to reveal the explanation.
Short Explanation
EIGRP doesn’t crown the link with the flashiest sticker speed—it scores the whole hike using the worst bandwidth hop and the delay pile-up. A “faster” NIC can still lose if the path’s composite score is worse. Look at the calculated metric, not one interface’s brochure number.
Full Explanation
EIGRP best-path selection uses a composite metric (by default heavily influenced by minimum path bandwidth and cumulative delay). A single high-bandwidth interface does not guarantee the lowest metric if other hops or delay dominate. Hop count alone, variance alone, or equal installation of all loop-free paths are not how classic EIGRP chooses the successor.
