Open Shortest Path First (OSPF): OSPF is a link state algorithm in which it measures the delay or cost of each router. Each router in the network sends a packet with the corresponding timestamp. This timestamp measures the time of the packets traversed to and from a neighboring router. After the router collected the link state packets from its neighbors, it constructs a routing table using Dijkstra’s least cost algorithm. Thus, the OSPF works based upon the timestamp; if the node in the “Denver” is crashed then it passes the information more quickly to all other nodes in the network.

Open Shortest Path First (OSPF):

OSPF is a link state algorithm in which it measures the delay or cost of each router.

Each router in the network sends a packet with the corresponding timestamp. This timestamp measures the time of the packets traversed to and from a neighboring router.

After the router collected the link state packets from its neighbors, it constructs a routing table using Dijkstra’s least cost algorithm.

Thus, the OSPF works based upon the timestamp; if the node in the “Denver” is crashed then it passes the information more quickly to all other nodes in the network.
