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...
EIGRP Topology Table: The Complete Guide to Successors, Feasible Successors, and DUAL
The EIGRP topology table is the database that separates EIGRP from every distance-vector protocol that came before it. It holds every loop-free route an EIGRP router learns from its neighbors, not just the one it currently uses. That single design choice is why EIGRP can recover from a link failure in milliseconds instead of waiting...
Successor, Feasible Successor, and Feasible Distance
DUAL relies on three closely related concepts to decide which route goes in the routing table and which routes stand ready as instant backups. This guide defines each one precisely, works through a real Feasibility Condition check using the same topology and numbers established in How to Calculate EIGRP Metric, and covers how OSPF’s fundamentally...
