Router / Switch Emulators or Simulators

[glen.krinsky]

I am looking for a router/switch simulator or emulator that I can use to test configurations and changes without using equipment.  All the one's I have found are geared to the CCNA/CCNP exams and are not fully functional.  Anyone have any ideas?

Hi Glen,

I suffered from the same experience. I suppose that nothing will fully replace the real equipment. For router emulation you can use for example GNS3, but when you come to switching it is a bit difficult. You can't emulate a switch ASIC and Cisco Packet Tracer haven't got implemented many features. So at some point you just need to configure real devices in lab. I have seen some sites offering remote access to cisco devices for learning purposes but they are not for free. I hope you will manage to get to the real devices for free so you can study and fully prepare for the exams!

Best regards,

Jan
