by We have implemented back a few bgp communities on our backbone. Below a small guide about how to use it.
Bloc announcement to a specific upstream of 34872
Community: 34872, 21, <dst_asn>
This community tell to as34872 router to don’t announce the prefix to a specific upstream. It work with our mains transit only. If you need to filter one not listed, let us know by ticket and we can add the filter.
To filter direct session over route server, you need to use the ixp community directly to filter out the required member over their route server.
