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...
How to Calculate EIGRP Metric: A Worked Example
EIGRP automatically calculates the routing table metric to choose the best path, but understanding exactly how that number gets produced turns an abstract routing table entry into something you can verify by hand. This guide works through a complete, real calculation step by step, using a topology consistent with the rest of this site’s EIGRP...
EIGRP Composite Metric: The Formula, K-Values, and a Worked Example
A composite metric is a single number calculated from several different path characteristics, used to determine the preferred route to a destination. EIGRP uses bandwidth and delay by default, but the formula technically accounts for two additional factors — load and reliability — that are available but not recommended for typical use. This guide covers...
