Difference between Distance Vector & Link-state Protocol are
as follows-

a) Distance vector protocol uses distance or hop count as
its metric to determine its best path to particular
destination, where as link-state protocol using current
congestion, cost as well as speed to determine its best path
to particular destination.

b) Distance vector protocol works by using Bellman ford
algorithm where as link-state protocol using Dijkstra algorithm.

c) Distance vector protocol sends update using broadcast,
where as link-state protocol sends updates using multicast.

d) Distance vector protocol sends periodic updates after a
regular interval, where as link-state protocol sends updates
if there is any changes in the network.

Note: Link-state protocol (Such as OSPF) sends entire
database after every 30 min.

e)Distance vector protocol sends it best route to other
router, where as link state protocol sends its links to
other routers.

f) Distance vector protocol is a classfull protocol i.e.
doesn't sends subnet mask information along with routing
updates, where as link state protocol is a classless
protocol, i.e. sends subnet mask information along with
routing updates.

g) Distance vector protocol doesn't support VLSM & CIDR
where as link-state protocol support VLSM & CIDR.


Thats all about difference between DV & LS. If anyone knows
somemore points thn plzzzzzz include...!!!

Answer / jitendera sina

shain your answer is correct but what about the second para of that question

it is a completely theoretical answer.
write down any where what i am writing here

in the link state routing protocol the router send its routing table to only its link router.in another way which is directly connected to it

where ever in the distance vector whole routing table is delivered to the all router in the network.
that is broad cast to all router
it is the best answer in any interview because its contain all information which you wrote above


and i am agin saying to all of the student who are prepairing for the interview/ccna plz try to give the answer what ever some one is given or not or it is wrong or wright
do not be affredd so say what you think
this might be possible that here u could be wrong but it is better to be wrong here
instead of in interview panel

Answer / shahin

Distance-vector routing protocols advertise routes to
neighbors, but a link-state routing
protocol advertises a list of its connections.





Jitu, i m not agree with u, the concept u wrote above.

Go through

Page 106".....

Answer / jitendera kumar sinha

ha ha
I know u never be aggry with me but you may be wright but as far as my knowledge is concern i am wright but i will go through that book
you also look in ccna todd lamle book i didn't remember page number right now but i think the topic is in the start of the book in chapter in which routing protocol started

Please have a look

or issme gussa kane ki koi baat nahi hai.mai galat ho saktha hun.its may be possible
