 In which routing method do all the routers have a common database ?

  • A.Distance vector
  • B.Link state
  • C.Link vector
  • D.None of these

Answer: B

Correct answer: Link state

In a link state protocol every router floods a description of its own links to all the others, so each ends with the same map of the network and computes its own shortest paths from it. Distance vector routers exchange only their own distance tables and never share a common database.
