OpenBGPD on Ubuntu 24.04

Overview

OpenBGPD is a free implementation of BGP, the routing protocol that ties networks together across the internet and inside large data centres, written by the OpenBSD project with a strong focus on security, correctness and a small, auditable code base. It runs as a single daemon, bgpd, that you configure with a clear, readable text file and operate with a companion control utility, bgpctl, that shows sessions, routes and policy at a glance. It speaks BGP to your routers as a peer, learns and advertises routes, and can act as a route server, a route reflector, an edge speaker or an RPKI validating router that filters routes against signed origin data. It uses privilege separation and a chroot so the network facing code runs with almost no privilege, keeps its routing tables in memory, supports IPv4 and IPv6, and gives you a powerful filter language for controlling exactly what it accepts and announces.

Common uses

• Run a secure route server, route reflector or edge BGP speaker from a readable config file
• Filter and validate routes with a powerful policy language, including RPKI origin validation
• Peer with your own routers to exchange, steer or blackhole traffic across your network
