ExaBGP allows engineers to control their network from commodity servers. Think of it as Software Defined Networking using BGP by transforming BGP messages into friendly plain text or JSON.

It comes with an healthcheck application to help you monitor your daemons and withdraw dead ones from the network during failures/maintenances. A full lab explaining how to use it is available here.

Find what other users have done with it. Current documented use cases include DDOS mitigation, network visualisation, anycast, service high availability.

The program is packaged for Debian, Ubuntu, ArchLinux, Gentoo, Mint, FreeBSD, OSX and even OmniOS, but the rate of development mean that some features may only be available on latest version.

ExaBGP does not perform any FIB manipulation. If this what you need, use another open source BGP daemon such as BIRD or Quagga.

##Support

Multiple versions can be used simulteanously without conflict when ExaBGP is ran from extracted archives and / or local git repositories.

The configuration file format changes from version to version, but effort are made to make sure backward compatibility is kept, however users are encouraged to read the release note and check their setup after upgrade.

##Commercial Support

You do not need commercial support to get help ! We try to be reactive to any problem raised, and hopefully are not too bad at it.

That said, some organisation are unable to deploy an application without commercial support, therefore it is available if your organisation requires it but is by no way required.
