Recomendacion: Para lograr obtener el mayor tráfico por STIX se tienen que seguir los siguientes lineamientos :

Realizar las mismas publicaciones BGP que se realizan a los carriers o quien tengan contratado TIP (Transporte IP).
Anunciar adicionalmente en STIX subneteo /24. Este anuncio es de ruta más especifica y es uno de los parámetros más importante por el cual BGP determina la ruta a ser seleccionada.
Configurar el prepend a los carriers con valor de al menos "3″ o más. Este parámetro es la variable para ir modificando el comportamiento del tráfico de entrada.
