In EIGRP, what is the role of K-values?

• A. They set the maximum hop count
• B. They define the components of the composite metric used for route selection
• C. They control the number of neighbors formed
• D. They configure hello timer intervals

Answer: (B)

In EIGRP, path selection is guided by a composite metric that combines several path characteristics. The K-values are the weights that determine how much each characteristic contributes to that metric. Each K-value corresponds to a metric component: bandwidth (K1), load (K2), delay (K3), reliability (K4), and MTU (K5). If a K-value is set to zero, its corresponding component is ignored in the calculation. By adjusting these values, you bias route selection toward certain qualities—such as higher bandwidth or lower delay—depending on network needs. With default settings, bandwidth and delay have the most influence, shaping how routes are chosen. So, the role of K-values is to define the components of the composite metric used for route selection (and how much each component weighs into the decision). They don’t set maximum hop counts, neighbor counts, or hello timer intervals.
