Re: [routing-wg]On BGP Communities

Hello Max,

Thanks for your interest in our work.

The answer is yes.

The list of communities we used in our work is freely available at  
the following URL: http://inl.info.ucl.ac.be/system/files/ 
CommunityTaxonomy-DataBase.xml_.gz
This list is documented following our taxonomy.

This is presented as an XML file.

The next step in our work would be to propose to the community an on- 
line database that could be queried by anyone to get information on  
BGP communities.  This database should also allow ISPs to document  
their own communities.
Keep on Rockin'
