En el enlace de referencia, explican muy bien el procedimiento para sumarizar rutas cidr.
He implementado en C# el procedimiento, y esta es la utilidad que me ha salido:
Lo primero es editar las rutas cidr a sumarizar en el richtextbox1.
Una vez editadas, pulsamos el botón sumarizar y obtenemos en el textbox1 la ruta cidr sumarizada
y en el richtextbox2 el desglose de las rutas en binario para efectuar el cálculo de la sumarización.
El código en C#
