+# To find how to have freeDiameter load this extension, please refer to the freeDiameter documentation.
+#
+# The rt_un_number extension is a simple showcase of load-balancing routing with
+# freeDiameter. It routes the messages to different servers based on a numerical
+# value contained in the User-Name.
+
+# The format of this configuration file is very simple, just declare
+# the list of all servers you whish to load-balance between.
+# serv = "server1.identity" ;
+# serv = "server2.identity" ;
