Distance vector routing is so named because it involves two factors: the distance, or metric, of a destination, and the vector, or direction to take to get there. Routing information is only exchanged between directly connected neighbors. This means a router knows from which neighbor a route was learned, but it does not know where that neighbor learned the route; a router can't see beyond its own neighbors. This aspect of distance vector routing is sometimes referred to as "routing by rumor." Measures like split horizon and poison reverse are employed to avoid routing loops.
Link-state routing, in contrast, requires that all routers know about the paths reachable by all other routers in the network. Link-state information is flooded throughout the link-state domain (an area in OSPF or IS-IS) to ensure all routers posess a synchronized copy of the area's link-state database. From this common database, each router constructs its own relative shortest-path tree, with itself as the root, for all known routes.

Answer / samyak
Distance Vector Protocol :
1-->Susceptible for routing loop
2-->Send updates periodically
3-->limited hop count
4-->send entire routing table to all of its neighbor
5-->Use Bell-ford algorithm
Link State Protocol :
1-->Provide loop free path
2-->Create topology table to find out best path to
destination network .
3-->send triggered update ,when topology changes.
4-->support unlimited hop count
5-->Use SPF algorithm to find out best path

Answer / jitendera
In distance vector routing protocol routing update will
send in the direction from the direction it is coming
in the link state the routing update will not be forwarded
from the direction it is coming

GUY i Have attended one interview for the data craft and they are offering me L1 postion and i am working at l2 in cisco so there is no way to get in the datacraft i am posting here the question he asked to and i have tested the interviewer and i come to know he was not having any knowledge. His questions are-: 1) what is Vlan 2) what is stp and what is difference between stp and RSTP 3) what is HSRP and Diffrence betwwen HSRP and GLBP 4) how to configure HSRP 5) Scenario Based question ( if we have two router and both are connected and there are having redundancy means two interface of the router r1 is connected to the two interface of Router R2 (R1)-------------(R2 (R1)-------------(R2 Now he want to configure the router in such a Manner that if one link down second link should come up.My answer was HSRP and his is "F looting static routing was i wrong "i know F looting Static routing is Theoretically possible but it is not fusible in the scenario where you have multiple router connected to the same router and if you have configured sub interface i challenged him and he lost The Battle and he get angary 5) what the eigrp and how it works 6) tables in eigrp 7) the information of feasible successor where it saved now after answering these all he was very angry ( i can fill the heat) 8) then he come to ospf Area type ( he was also not aware) 9) LSA type and its working ( he was also having confusion ) 10) then is asked routing by rummer( Theroy) 11) hello and dead intervel of EIGRp (theory) 12) Selection cretaria for Eigrp slecting best path ( here we have a long discussion on MTU and he lost the battle and agree That MTU never comes in the accounts in this process) 13) what is ACL type of acl ( here he was aware of TWO type Standard and extended i have told him 5 type( he again get Angry) We have 2hr of discussion and and he told me he will call me latter but i know he never call
