Open Shortest Path First (OSPF)

Open Shortest Path First (OSPF) is an Interior Gateway Protocol (IGP) standardized by the Internet Engineering Task Force (IETF) and commonly used in large Enterprise networks. OSPF is a link-state routing protocol providing fast convergence and excellent scalability. Like all link-state protocols, OSPF is very efficient in its use of network bandwidth.

 

Cisco is an active member of the OSPF working group at the IETF, and is responsible for many of the ongoing enhancements to the protocol.
