OpenOSPFD is an ISC licensed implementation of the Open Shortest Path First Protocol.

It is a network routing software suite which allows ordinary general purpose computers to be used as routers exchanging routes with other computer systems speaking the OSPF protocol.

OpenOSPFD was developed by Esben Nørby and Claudio Jeker, for the OpenBSD project.

OpenOSPFD is developed on OpenBSD, and ports exist for FreeBSD and NetBSD.

The design goals of OpenOSPF include being secure (non-exploitable), reliable, lean and easy to use.
