About the NL-ix Looking Glass

The Looking Glass runs OpenBGPD as backend. The front-end is based off of the open source software written by Teun Vink, which can be seen here on GitHub. The code was inspired on bird-lg by Mehdi Abaakouk.

Known BGP Communities

This Looking Glass uses a collection of known BGP communities to provide additional information on routes received. A list of ASNs for which communities are known can be found here.

New community descriptions and updates can be added sending a pull request on the Github repostory, which also provides information on the file format. For any questions, feel free to contact the ring-admins@nlnog.net.
