What is OSPF?

If you are looking for a routing protocol that provides dynamic network connectivity between two endpoints, then OSPF may be the right one. It’s designed to overcome some of the limitations of RIP and link state protocols and is more efficient than other routing protocols

The acronym OSPF stands for Open Shortest Path First. It’s a routing protocol that provides dynamic network connectivity between two endpoints on an IP network via the shortest path from one router to another in a LAN. Originally developed by the Internet Engineering Task Force (IETF) in 1989, it was designed to overcome some of the limitations of RIP and link state protocols. One major difference is that OSPF has no broadcast or multicast capabilities, which makes it more efficient than other routing protocols.

Benefits:

  • OSPF is an open-standard protocol that doesn’t require a license to use.
  • It provides dynamic connectivity between two points. A routing protocol can only provide static connections, meaning you have to configure the route every time something changes and there are no automatic adjustments for links going down or up. With OSPF, any change will be automatically updated so you don’t need to worry about reconfiguring anything after making a configuration update!
  • Another great thing about this protocol is its scalability; running large networks with many routers becomes less complicated because the architecture scales well as more devices are added into the environment.
