GATE | GATE-CS-2014-(Set-2) | Question 65

Which one of the following is TRUE about interior Gateway routing protocols – Routing Information Protocol (RIP) and Open Shortest Path First (OSPF)
(A) RIP uses distance vector routing and OSPF uses link state routing
(B) OSPF uses distance vector routing and RIP uses link state routing
(C) Both RIP and OSPF use link state routing
(D) Both RIP and OSPF use distance vector routing


Answer: (A)

Explanation: Both Routing Information Protocol (RIP) and Open Shortest Path First (OSPF) are Interior Gateway Protocol, i.e., they both are used within an autonomous system.

RIP is an old protocol (not used anymore) based on distance vector routing.

OSPF is based on Link State Routing.
