Project Summary
OpenBGPD is a FREE implementation of the Border Gateway Protocol, Version 4. It allows ordinary machines to be used as routers exchanging routes with other systems speaking the BGP protocol.
Started out of dissatisfaction with other implementations, OpenBGPD nowadays is a fairly complete BGP implementation, powering many sites. Users often praise its ease of use and high performance, as well as its reliability.
OpenBGPD's companion, OpenOSPFD, adds support for the OSPF protocol suite.
OpenBGPD is primarily developed by Henning Brauer and Claudio Jeker; OpenOSPFD also by Esben Nørby. Both are part of the OpenBSD Project. The software is freely usable and re-usable by everyone under a BSD license.
