In EIGRP, what is the term for the router's metric value to the route's destination?

In EIGRP (Enhanced Interior Gateway Routing Protocol), the term that refers to the router's metric value to the route's destination is known as Feasible Distance (FD). The Feasible Distance is the total distance or metric that a router calculates to reach a specific destination network, factoring in its own cost to reach that destination.

This value is crucial for EIGRP's decision-making process in route selection. Each router keeps a record of the Feasible Distance for all possible routes to a destination in its routing table, and it uses this information to determine the best route to use for forwarding packets. The route with the lowest Feasible Distance is preferred.

Understanding the concept of Feasible Distance is essential for analyzing how EIGRP handles multiple paths to destinations and makes routing decisions, especially in scenarios involving unequal-cost load balancing and route reliability.
