In OSPF, what routing metric is used to select the best path?

Explanation:
OSPF chooses the best path using a cost metric that is added up across the route. Each link running OSPF gets a cost based on its bandwidth, and the router uses the Shortest Path First algorithm to build a shortest-path tree. The route with the lowest total cost is the one that traffic follows. The per-link cost is derived from a reference bandwidth divided by the interface’s bandwidth, so faster links contribute smaller costs. In short, the overall path cost is the sum of the per-link costs, and the lowest-cost path wins. Other metrics like hop count or delay aren’t how OSPF selects routes.
