Difference Between Distance Vector Routing vs Link State RoutingThe following article provides an outline for Distance Vector Routing vs Link State Routing. A router does not need to know the complete route to each network segment in distance vector routing; it just needs to understand the vector or direction in which to deliver the packet. This method calculates the distance, i.e. hop count and direction, i.e. vector to any network in an internetwork. On a regular basis, distance vector routing approaches broadcast parts of the routing table during their next neighbors. Therefore, even if there are no changes in the network, routers using the distance vector routing protocol will provide frequent updates. Based on updated information received from neighbouring routers, a router verifies all known routes as well as make modifications to its local routing table. Because the routing knowledge a router possesses of the network topology is dependent on the perspective of the routing table of the neighbour router, this approach is known as “routing by gossip.”A typical distance vector protocol which uses routing metrics or hops counts are RIP and IGRP. In link-state routing, every router attempts to create its internal map of network infrastructure. When the router first becomes operational, it transmits messages to the network and gathers data from routers with whom it is connected directly. It tells you whether or not the link to the router is active. Other routers utilise this information to create a network topology map. The router then scans the map to select the best route. The link-state routing methods respond quickly to changes in the network. It delivers triggered updates if there is a change in the network and periodic updates every 30 minutes. If the state of the link changes, the device that detected the change generates and sends an update message to all routers. The message is then forwarded to all neighbouring routers once each router receives a copy of the update message as well as updates its routing database. The update message must be flooded to guarantee that all routers update their databases before generating an update routing table that incorporates the new technology. The OSPF protocol is an example of link state routing.

ConclusionThe information of the completely autonomous system and the data is shared only with neighbours in distance vector routing. In link state routing, on the other hand, routers communicate just information about their neighbours; the information is shared among all routers.
