Hi,
Some One Ask me the 10 difference between Distance vector and Link State??
But I know only one or two pls help us to provide the details.
Solved! Go to Solution.

Are these homework questions.........
Well I am brushing up on this myself and I had a hard time getting ten but here are five....I think....anyone please correct me if I am wrong.
Distance-Vector updates only directly connected routers and Link-State updates every router in it's area.
Distance Vector sends update periodically and Link-State sends updates only when something has changed
Distance Vector send it whole routing table when it updates and Link-State only send the state of its Interfaces
Distance Vector can't "see" the network beyond its neighbors and Link-State "sees" the entire network (Area)
Distance Vector needs a way to prevent routing loops as it cannot see the entire network and Link-State sees everything and does not have routing loops.
Please remember to rate posts that help.

Abhinay,
Well, while it is certainly possible to find 10 differences between LS and DV routing protocols, there is hardly any "common set of differences". I am not quite sure which differences was that person interested in.
Think of differences in the following areas:

Abhinay,
Well, you're correct, DV protocols use a distributed form of Bellman-Ford algorithm while the LS protocols use the Dijkstra algorithm.
Best regards,

Came up with a few more and check this link out and look at the section about Link State vs Distance Vector
http://www.cisco.com/en/US/docs/internetworking/technology/handbook/Routing-Basics.html#wp1020646
Distance Vector uses Hop count and Link State uses a shortest path to get to the destination
Distance Vector uses the Bellman-Ford Algorithm and Link State uses Dijkstra Algorithm
Distance Vector has a longer convergence and Link State's convergence is much quicker
Distance Vector uses less CPU and Memory and Link State is CPU and Memory intensive
Distance Vector is not that scalable and Link State is very scalable

Wow Peter great information thanks for sharing +5 for that!!
.
Thanks,

Thanks sir ji realy nice one...

Distance Vector uses the Dijkstra's Algorithm and Link State uses Bellman-Ford Algorithm
Thanks for reply but I have doubt in this...
