What do routing algorithms use to determine the best route?

Explanation:
Routing algorithms determine the best path by evaluating a numeric value called a metric for each potential route. This metric represents the cost of using that route and can reflect factors like hop count, bandwidth, delay, reliability, or administrative policy. The route with the lowest metric is chosen as the best path and used to forward packets. IP addresses identify where a packet is going, but they aren’t used to compare routes. Hostnames are human-friendly labels and aren’t used by routers to decide paths. Routes learned from neighbors provide possible options, but the decision comes down to comparing their metrics.
