OSPF (Routing Protocol)

For big networks in the internet what we need is a network path which is shorter and best. OSPF is a routing protocol which enables data packets to choose the best path. It is widely popular IGP (Interior Gateway Protocol) which is implemented by most of the major network providers. OSPF stands for open shortest path first, this protocol determines the best path for routing the data traffic. OSPF does routing based on cost calculation, the path with lowest cost always gets the priority. Consider the example below in this network the lowest cost is 10 hence the packet chooses the path with lowest cost to reach the destination.
