Este exemplo de configuração mostra a criptografia totalmente em malha entre três roteadores através do uso de um mapa de criptografia em cada roteador para as redes atrás de cada um de seus dois pares.
A criptografia deve ser feita de:
Rede 160.160.160.x para rede 170.170.170.x
Rede 160.160.160.x para rede 180.180.180.x
rede 170.170.170.x para rede 180.180.180.x
