When EIGRP learns the same route from two paths, which parameter selects the best path?

EIGRP uses its composite metric to determine the best path when multiple routes to the same destination are learned. This metric is calculated using bandwidth, delay, reliability, and load, with bandwidth and delay being the primary factors by default. The path with the lowest metric is preferred. Administrative distance (AD) is used to select the best route when a router learns the same route from different routing protocols (e.g., EIGRP vs. OSPF), not between multiple paths within the same protocol. AS-path is a BGP attribute, not used by EIGRP. "Cost" is a general term for a route's value, but EIGRP specifically uses its composite metric calculation.
