Este documento muestra el encripción de red radial de un router (el "eje de conexión") a tres otros routers (los "radios"). Existe un mapa de encripción en el router hub que especifica las redes detrás de cada uno de sus tres pares. Los mapas de criptografía de cada uno de los routers radiales especifican la red que hay detrás del router hub.
El cifrado se realiza entre estas redes:
red 160.160.160.x a red 170.170.170.x
160.160.160.x red a 180.180.180.x red
red 160.160.160.x a red 190.190.190.x
No hay requisitos específicos para este documento.
