Which metrics does EIGRP use for path selection?

EIGRP (Enhanced Interior Gateway Routing Protocol) utilizes a set of metrics for path selection that are designed to provide a comprehensive view of the potential routes available in a network. The primary metrics used by EIGRP are bandwidth, delay, load, and reliability.

Bandwidth refers to the maximum data rate that can be accommodated on a network interface, while delay indicates the time it takes for data to travel from the source to the destination. Load and reliability further refine the assessment of a path. Load measures how much of the bandwidth is currently being utilized, and reliability assesses the link's stability based on historical performance.

By taking all these metrics into account, EIGRP can make more informed routing decisions, allowing it to efficiently determine the best path to a destination. This multi-metric approach not only enhances performance by optimizing route selection but also accommodates various network conditions, ensuring resilience and efficiency in routing.
