UNICAST ROUTING

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Link state routing uses ____ algorithm.
A
Quick Sort Algorithm
B
Floyd Warshall Algorithm
C
Bellman Ford
D
Dijkstra’s
Explanation: 

Detailed explanation-1: -The Link state routing algorithm is also known as Dijkstra’s algorithm which is used to find the shortest path from one node to every other node in the network.

Detailed explanation-2: -Dijkstra’s algorithm, also known as the Link state routing algorithm, finds the shortest path from one node to all other nodes in the network. The Dijkstra’s algorithm is iterative, and it has the property that after k iterations, the least cost paths for k destination nodes are well known.

Detailed explanation-3: -EIGRP uses Diffusing Update Algorithm (Advanced Distance-Vector Routing Protocol), and both IS-IS and OSPF use Dijkstra’s Algorithm (Link-State Routing Protocol).

Detailed explanation-4: -After each router’s database is completed, the router calculates a Shortest Path Tree to all destinations. The router uses the Dijkstra algorithm to calculate the shortest path tree.
