what is distance vector protocol link state protocol and
what is the diffrence between them

Answer Posted / jagrit

EVERY ONE IS WRONG

Distance-Vector Routing Protocols:-

This type of routing protocol requires that each router simply inform its neighbors of its routing table. For each network path, the receiving routers pick the neighbor advertising the lowest cost, then add this entry into its routing table for re-advertisement. Hello and RIP are common D-V routing protocols


Link State Routing Protocols:-

This type of routing protocol requires each router to maintain at least a partial map of the network. When a network link changes state (up to down, or vice versa), a notification, called a link state advertisement (LSA) is flooded throughout the network. All the routers note the change, and recompute their routes accordingly. This method is more reliable, easier to debug and less bandwidth-intensive than Distance-Vector. It is also more complex and more compute- and memory-intensive
