OSPF Routing

39.5k

OSPF stands for Open Shortest Path First. Two routers communicating via OSPF share information about the routes they are aware of and the cost of getting there. To find the shortest path via the network between themselves and a remote router or network destination, OSPF routers use cost.

The first benefit of OSPF is its scalability. OSPF allows the network to grow as it becomes more complex because it can manage a larger network area. In contrast, other protocols such as RIP cannot handle the increased complexity and the length of their routing tables becomes unmanageable as the network expands. The second benefit that OSPF offers is stability. Unlike other routing protocols, OSPF uses link-state updates to advertise only changes in routes instead of periodic announcements about all active routes in its topology table. This means that when there are no changes in the topology, routers

Because OSPF is a link-state routing protocol, it is mostly utilised for internal routing. The OSPF protocol is based on Dijkstra's method for calculating the shortest path between two sites.

The OSPF are designed to reduce routing traffic while also reducing the processing load on your core routers. Through the Area Border Router, different areas are linked together (ABR). OSPF stands for Open Shortest Path First, and it is possible to tune a link state routing protocol to converge quickly.
