These divided areas can be a collection of hosts, routers, and networks. In OSPF, the Autonomous system is divided into areas to avoid the high traffic which is caused by flooding. Refer to the below image to show the OSPF areas OSPF protocol is the protocol that works based on the link state routing algorithm in which each router has the information about each domain and uses this information to determine the shortest path.Intradomain protocol means that this protocol is used within the network or an area.
OSPF is used within the autonomous system and it divides the autonomous system into different areas.
OSPF protocol is based on the link state routing algorithm. This protocol is used for exchanging information between the dynamic routers. OSPF stands for Open Shortest Path First and it is an intradomain protocol.
