QUEMU      QUEDA TAL COMO ESTA




Arrastramos las imagens que requerimos routers y switch

Seleccionamos los 2 routers y click derecho sobre uno de ellos y elegimos configure
Y nos sale el siguiente menu




Vamos a slot y cambiamos donde dice wic 0 y elegimos WIC-2T
Apply y OK




Luego damos click en add link
Damos click sobre alguno de los objetos y nos muestra las interfaces para seleccionar ,
elegimos y apare automáticamente el cable para conectar a otro objeto a alguna de sus
interfaces




Una vez realizados las conexiones damos click en el icono que tiene la forma de un triangulo
verde
Al aparecer todos los puntos en verde significa que la estructura esta trabajando con
normalidad.

Luego damos click en le botón consoletoalldevice




Y aparece las siguientes ventanas
Nos percatamos que el rendimiento es pésimo del S.O. por lo cual, primero damos click en el
botón add link para que vuelva a su icono original, luegoselecionamos una de los routers y
damos click en Idle PC , aparece un cuadro y damos YES
Aparece un cuadro como el de la imagen




Damos click en la pestaña y seleccionamos alguno de los números que empiezan con *
damos aply y luego OK y con esto se reduce el consumo del CPU.
