BGP Swiss Army Knife ExaBGP provides a convenient way to implement Software Defined Networking by transforming BGP messages into friendly plain text or JSON, which can then be easily handled by simple scripts or your BSS/OSS. It is routinely used to improve service resilience and provide protection against network or service failures. For example, thanks to the healthcheck backend included, anycasted DNS service failures can be detected and handled gracefully. To help you get started, Vincent Bernat put forward a full lab explaining how to best use this feature. Also, alone or in conjunction with fastnetmon, it provides network operators a cost effective DDOS protection solution. But it is not its only strength, thanks to modern routers’ flow balancing, ExaBGP can also be used to save you money on load balancers. Other uses include keeping an eye on network changes done by RIPE or by other networks with GIXLG. For years, ISP have been using BGP and custom code to per...
