Hi everyone,

Maybe most of you know this but I'm gonna post it for others that didn't know about.

If you need a good simulator (actually emulator)for CISCO & Juniper Routers use GNS3.

From GNS3 Web:


What is GNS3 ?

GNS3 is a graphical network simulator that allows simulation of complex networks.


To allow complete simulations, GNS3 is strongly linked with :

Dynamips (http://www.ipflow.utc.fr/index.php/Cisco_7200_Simulator), the core program that allows Cisco IOS emulation.
Dynagen (http://www.dynagen.org/), a text-based front-end for Dynamips.
Qemu (http://www.qemu.org/), a generic and open source machine emulator and virtualizer.
GNS3 is an excellent complementary tool to real labs for network engineers, administrators and people wanting to pass certifications such as CCNA, CCNP, CCIP, CCIE, JNCIA, JNCIS, JNCIE.
It can also be used to experiment features of Cisco IOS, Juniper JunOS or to check configurations that need to be deployed later on real routers.
This project is an open source, free program that may be used on multiple operating systems, including Windows, Linux, and MacOS X.


Direct download link Download GNS3 from SourceForge.net (http://downloads.sourceforge.net/project/gns-3/GNS3/0.7.4/GNS3-0.7.4-win32-all-in-one.exe?r=&ts=1303409714&use_mirror=heanet)

More information will be found at GNS3 | Graphical Network Simulator (http://www.gns3.net)

Hi Guys,

Do you have OS ?
I found some links which contains IOS images for Cisco Routers which you can use :

ftp://ftp.unikon-ua.net/pub/Cisco/IOS/
ftp://62.117.115.92/upload/ios/
http://www.jonsfiles.com/IOS%20Images%20for%20GNS3/Cisco_IOS_Collection/IOS/

Or for more check this web site: Cisco Ios Collection For Gns3 And Actual Routers. | All About Networking. (http://networkingtips-tricks.blogspot.com/2010/03/cisco-ios-collection-for-gns3-and.html)

If you need anything else, ask and I'll try to help :)
