Question

Accepted Answer

OSPF is a routing protocol used in computer networks to determine the best path for data to travel.

OSPF stands for Open Shortest Path First.
It is a link-state routing protocol.
It uses Dijkstra's algorithm to calculate the shortest path.
OSPF routers exchange information about their connected links to build a topology map of the network.
This allows the routers to determine the best path for data to travel.
OSPF is commonly used in large enterprise networks.
It is also used in internet service provider networks.
OSPF is more complex than other routing protocols like RIP or EIGRP.
It provides better scalability and faster convergence times.
OSPF has different types of routers, including backbone routers, area border routers, and internal routers.
