Reported Distance and Feasible Distance in EIGRP: Navigating the Routing Landscape

Enhanced Interior Gateway Routing Protocol (EIGRP) is a robust solution for efficient routing in computer networks. As networks become complex, understanding the intricacies of EIGRP metrics becomes crucial. Among these metrics, reported and feasible distances are pivotal in determining the optimal routes.

What is EIGRP?

EIGRP, or Enhanced Interior Gateway Routing Protocol, is a sophisticated routing protocol designed to enhance the efficiency and speed of data routing within a network. Its advanced features make it a popular choice for network administrators seeking seamless communication.

Routing Metrics in EIGRP

In EIGRP, routing metrics evaluate and select the best routes. Reported and feasible distances are integral to these metrics, influencing how data is directed through the network.

Reported Distance Explained

Reported distance refers to the cumulative metric from a neighboring router to a specific destination. Calculated based on bandwidth and delay, it offers insights into the overall path cost.

Feasible Distance Unveiled

On the other hand, feasible distance represents the metric of the best path to reach a destination. It includes the reported distance and accounts for additional factors like reliability and load.

Relationship Between Reported and Feasible Distance

The interplay between reported and feasible distance is critical. EIGRP selects routes based on the feasible distance, making it imperative to comprehend how these metrics interact for effective route determination.
