If you face any problem setting it up with GNS3 drop me a message and I will get back to you asap.
GNS3 is an open source (GNU GPL) software that simulates complex networks while being as close as possible from the way real networks perform, all of this without having dedicated network hardware such as routers and switches.
GNS3 provides an intuitive graphical user interface to design and configure virtual networks, it runs on traditional PC hardware and may be used on multiple operating systems, including Windows, Linux, and Mac OS X.
In order to provide complete and accurate simulations, GNS3 actually uses the following emulators to run the very same operating systems as in real networks:
- Dynamips, the well known Cisco IOS emulator.
- VirtualBox, runs desktop and server operating systems as well as Juniper JunOS.
- QEMU, a generic open source machine emulator, it runs Cisco ASA, PIX and IPS.
Cisco Ios Versions
GNS3 is an excellent alternative or complementary tool to real labs for network engineers, administrators and people studying for certifications such as Cisco CCNA, CCNP andCCIE as well as Juniper JNCIA, JNCIS and JNCIE.

| Other versions should also be supported following bellow’s procedure. IOL or IOS On Linux, also called IOU or IOS On Unix. IOL, is a simulator available for Cisco internal use only. IOL refers to the Linux version, compiled for i386 architecture. IOU refers to the Unix (Solaris) version compiled for Sparc architecture. The term IOU usually refers to IOL too. Because IOL is an internal IOS version, IOL can be used by Cisco employees or by authorized customers only. Upload the downloaded image to the EVE using for example FileZilla or WinSCP to: /opt/unetlab/addons/iol/bin/. Type following command to fix permissions: IOL images must end with the “.bin” extension and must be executable. License must be stored under the same path. IOU/IOL license is bound to the hostname and domain name of the server. A test should be made to check if IOU/IOL images can run properly. Google for how to create iourc license file. Bellow is an EXAMPLE how it should look like: If the IOL/IOU instance doesn’t start, then you won’t be able to use IOL/IOU nodes inside EVE. |
