How do routers use the routing table to determine the best path to a destination network?

0

Answer Hi Jacob, and thanks for your question. The work of determining the best path to a node is done by the router. It takes in route information from other nearby routers using a routing protocol, like OSPF (Open Shortest Path First), routes it learns about on its own, and static routing information. It then performs a calculation to determine the shortest path to all other networks. This calculation depends how “shortest Path” is determined. This can be by number of hops, or it can also take the speed of each link into account.
