Worth Reading: Visualizing BGP-LS Tables

When I’d first seen BGP-LS I immediately thought: “it would be cool to use this to fetch link state topology data from the network and build a graph out of it”. In those days the only open-source way I could find to do it involved Open DayLight controller’s BGP-LS-to-REST-API converter, and that felt like deploying an aircraft carrier to fly a kite.

Things have improved dramatically since then. In Visualizing BGP-LS Tables, HB described how he solved the challenge with GoBGP, gRPC interface to GoBGP, and some Python code to parse the data and draw the topology graph with NetworkX. Enjoy!
