Hello,
As has been mentioned in this thread there is currently no standardized
way for networks to communicate the meaning of the BGP communities they
support or attach to their prefixes.
I have authored an IETF draft that attempts to change this:
https://datatracker.ietf.org/doc/draft-ietf-grow-yang-bgp-communities/
Using the model described here, networks can publish a JSON file with
descriptions for the communities they use for their Autonomous System.
There are currently two networks with published community definitions
(RIPE NCC's AS25152 and AS197000) and one implementation that can parse
published definitions (NLNOG Looking Glass[0][1]). To further this
effort it would help if more networks started publishing their
communities using this format.
Kind regards,
Martin
