 Let us analyze the illustration above 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: Let us analyze the illustration above provided by RENATER to explain how to use communities on its network.
