Traffic between peering members does not cross the route-server, but goes directly from one member to another. Route-servers simplify the configuration of the members who use them.
In addition, the route-server can be used as a backup in case of maintenance or problems with any other BGP session.
The new CATNIX route-server operates on a Bird platform and its Autonomous System is AS60082. In case you would like to use it, you can contact catnix@suport.csuc.cat.
