Simulador de Router Cisco 7200 en un PC

Este proyecto, tiene como fin disponer de un router cisco 7200 virtual en tu propio PC, y así poder realizar pruebas y estudios del mismo sin poner en peligro la configuración de un router en producción.

Personalmente lo estoy probando y es realmente útil para quienes nos adentramos en el maravilloso mundo de las redes y routers :P

El modo de instalación es bastante sencillo, sería el siguiente:

1) Descargamos el binario ejecutable de dynamips:

• Executable for Linux/x86 (http://www.ipflow.utc.fr/dynamips/dynamips-0.2.7-x86.bin)
• Executable for Linux/x86_64 (AMD64 and EM64T)

2) Para un arranque más rápido, descomprimimos la imagen IOS del router Cisco 7200 (la imagen la podéis descargar del propio router):

$ unzip -p c7200-advipservicesk9-mz.124-9.T.bin > image.bin

3) Confirmamos que la nueva imagen ha sido creada correctamente:

$ file image.bin
image.bin: ELF 32-bit MSB executable, cisco 7200, version 1 (SYSV), statically linked, stripped

4) Y finalmente arrancamos la imagen:

$ ./dynamips-0.2.7-x86.bin dynamips-0.2.7/image.bin -t npe-400 -p 1:PA-A1 -p 2:PA-8T -p 3:PA-4E -p 4:PA-POS-OC3 -p 6:PA-FE-TX

Ya podremos comenzar a configurar el Router:
