There are several advantages of link state routing protocols.
Its build a topological map
Link-state routing  protocols creates a topological map of the network topology.Distacne vector protocol do not have the topological map.Router that uses the distance vector protocol only contain the list of the network, which include the cost that indicate the distance and next-hop router [...]

When there is no route defines the routing table for the destination network then only default static router are used. First connect two routers with a serial cable. Here one side of cable on router1 is acts as a DCE and the other side of cable on router 2 acts as a DTE.For making DCE [...]
