EIGRP calculates metrics from components:
Bandwidth: Minimum bandwidth along the path (in Kbps).
Delay: Cumulative delay along the path (in microseconds).
Reliability: Fraction of successfully received packets (-). Rarely used.
Load: Current traffic load on the link (-). Rarely used.
By default, only bandwidth and delay are used:
Metric = ( / minimum bandwidth) + (cumulative delay / ) *
This formula considers both capacity (bandwidth) and latency (delay). A high-bandwidth, high-delay satellite link won't automatically win over a lower-bandwidth terrestrial link.
