Buscando informacion sobre Cisco en la red me enconte con este proyecto, un emulador de cisco 7200 el cual crea un entorno virtual y hace botar la imagen IOS, claro, todo esto es con fines didacticoso o para ponerse a alusinar, o soñar que tenemos un router.

Lo interesante es que bota un IOS real, solo hay que descomprimirlo


$ unzip -p c7200-g6ik8s-mz.124-2.T1.bin > image.bin
warning [c7200-g6ik8s-mz.124-2.T1.bin]: 27872 extra bytes at beginning or within zipfile
(attempting to process anyway)

Ya descomprimido se corre el emulador:

$ ./dynamips image.bin -t npe-400 -p 0:C7200-IO-FE -s 0:0:udp:10000:127.0.0.1:10001 -p 1:PA-A1 -s 1:0:udp:10002:127.0.0.1:10003 -p 2:PA-8T -s 2:1:udp:10004:127.0.0.1:10005
