Why are link state protocols more efficient than distance vector routing protocols?

Why are link state protocols more efficient than distance vector routing protocols?

Link state protocols are also called shortest-path-first protocols. Link state routing protocols have a complete picture of the network topology. Hence they know more about the whole network than any distance vector protocol.

Which type of routing protocols converge the fastest?

EIGRP has the fastest router convergence among the three protocols we are testing.

What is the main difference between distance vector routing and link state routing?

The prior difference between Distance vector and link state routing is that in distance vector routing the router share the knowledge of the entire autonomous system whereas in link state routing the router share the knowledge of only their neighbour routers in the autonomous system.

What are the advantages of link state routing protocols?

Fast Network Convergence: It is the main advantage of the link-state routing protocol. Because of receiving an LSP, link-state routing protocols immediately flood the LSP out of all interfaces without any changes except for the interface from which the LSP was received.

Why does link state converge faster than distance vector?

Additionally, link state convergence occurs faster than distance vector convergence. This is because link state establishes a neighbor relationship with directly connected peers and shares routing information with its neighbors only when there are changes in the network topology.

When would you choose a link state protocol instead of a distance vector protocol?

If the answer is the router needs to learn about all paths then that protocol is Link-State, if it only needs to learn paths between different neighbors then the protocol is Distance Vector.

What does it mean if a routing protocol converges to a steady state quickly?

What does it mean if a routing protocol converges to a steady state quickly? Changes to the network topology are propagated between routers quickly. This makes the network quicker and more reliable.

How does the speed of convergence affect the network?

Convergence time A larger network will converge more slowly than a smaller one. In case of a new route being advertised, triggered updates can speed up RIP’s convergence but to flush a route that previously existed takes longer due to the holddown timers in use. OSPF is an example of a fast-converging routing protocol.

Why is link state better than distance vector?

Which distance vector characteristics can speed up convergence?

When using holddowns, triggered updates, split horizon, and poison reverse updates, routing protocols (such as IP RIP) can avoid routing loops, which helps to speed up convergence.
