OpenBGPD is a BGP (Border Gateway Protocol) v4 daemon. The border gateway protocol is a protocol that is used by routers to route internet traffic, so any computer running OpenBGPD is essentially a router.
It is part of the OpenBSD project, however it is released separately – intended to be a simple, secure, and reliable routing package.
