What are the advantages of using Distance Vector Routing ?
Advantages of Distance Vector Routing are : Large Routing Tables High network traffic overhead. Route advertising is done periodically even after the internetwork has converged. Multiple routes to a given network ID can be reflected as multiple entries in the routing tables. Doesn't scale. Disadvantages of Distance Vector Routing are : 1. It is slower to converge than the link state. 2. It is at risk from the count-to-infinity problem. 3. It creates more traffic than link-state since a hop count change must be propagated to all routers and processed on each router. Hop count updates take place on a periodic basis, even if there are no changes in the network topology, so bandwidth-wasting broadcasts still occur. 4. For larger networks, distance vector routing results in larger routing tables than link-state since each router must know about all other routers. This can also lead to congestion on WAN links.
