Calculating the Best Routes for the Routing Table
Path Selection
EIGRP calculates the metric for routes much differently than any other routing protocol. For instance, with OSPF, anyone with a network diagram and knowledge of the configured OSPF interface costs can calculate the exact OSPF metric (cost) for each route.

The EIGRP composite metric means that EIGRP feeds multiple inputs (called metric components) ...
