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:
(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:
There are Two most common Routing algorithms.
1. Distance-Vector: Each router exchanges information about the entire network with neighbouring routers at regular intervals.
2. Link-state: Each router exchanges information about its neighbourhood with all routers in the network when there is a change.
-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 any-more) based on distance vector routing.
-OSPF is based on Link State Routing.
