Request for BGP Community-to-text mappings for BGP Looking Glass

Fri Sep 23 16:01:55 UTC 2022

Dear all,

I'd like to ask help from the EBGP hivemind: the shiny new BGP looking
glass at https://lg.ring.nlnog.net/ supports displaying text strings
mapped from BGP community values (both simple and large communities).

Mapping BGP Community values to simple English human-readable text
phrases can help network operators better understand what the heck is
going on.

An example can be seen here, if you hover your mouse pointer over
2914:3200 you'll see "Europe":
https://lg.ring.nlnog.net/prefix?q=2001%3A67c%3A208c%3A%3A&match=exact&peer=all

This looking glass does not cache results, it is real time.  What's
displayed on the website comes straight from the route collector's BGP
daemon.

Contributing mappings is very easy: just send pull-requests for files
in this directory: https://github.com/NLNOG/lg.ring.nlnog.net/tree/main/communities
The data format supports wildcards and ranges in case blocks of BGP
communities basically mean the same thing.

Please consider submitting what you know! The more the merrier. 

[ disclaimer & welcome sign: Anyone can contribute! You don't need to be
  the holder of a given ASN to submit comm2text mappings for that ASN.
  All data is user-submitted. No attempt is made to validate the
  mappings for accuracy. ]

Shout out to Teun Vink for authoring this very pretty webinterface for
OpenBGPD's JSON web API!

Kind regards,

Job
