 ====== BGP Communities in Practice ======
-BGP communities enable to label prefixes announced by BGP in order to apply specific policies. Two good examples of using BGP communities in real networks are provided for [[https://www.sprint.net/index.php?p=policy_bgp | Sprint]] and [[https://services.renater.fr/connectivite/routage_d_adresses | RENATER]].

 Let us analyze the illustration below provided by RENATER to explain how to use communities on its network. A dual-connected client network identifies a primary link and a secondary or backup link toward RENATER. In the BGP prefix announcements, this network can use the community ''2200:610'' on the primary link, and the community ''2200:590'' on the backup link. RENATER applies specific policies in order to implement the primary/backup behavior. A simple way to do this is described in the following:
