How is link state routing different from distance vector routing?


Asked by Sylas Lloyd on Dec 11, 2021 FAQ



Just like the Distance Vector Routing Protocol, this routing protocol also has some limitations, though it tries to resolve some of the issues arising in the former one. Link state routing protocol reduces the network data overhead, unlike distance vector routing protocol, by using partial computation when a link metrics changes in the network.
Subsequently,
Distance Vector Routing Protocol (DVRP) Definition - What does Distance Vector Routing Protocol (DVRP) mean? Distance Vector Routing Protocol (DVRP) is one of two major routing protocols for communications methods that use data packets sent over Internet Protocol (IP).
Accordingly, Common routing protocols include RIP, RIPv2, IGRP, EIGRP, IS-IS and BGP. For the CCNA exam you will need to be well versed in RIP, RIPv2, IGRP and EIGRP. You should be aware of IS-IS and BGP, and be able to configure basic OSPF.
Besides,
The Link state routing algorithm is also known as Dijkstra's algorithm which is used to find the shortest path from one node to every other node in the network.
Also,
The process of DSDV is same as that of Distance Vector Routing but an extra attribute of sequence number is added. DSDV protocol uses and maintains a single table only, for every node individually. The table contains the following attributes.
