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.
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.
One of the most commonly used software to prepare for the Cisco exams is GNS3. To use network devices such as Router, Switch on the GNS3 emulator, you must download Cisco images.

GNS3 is more specific and professional than Cisco Packet Tracer. There is no need to add any Cisco devices to the Packet Tracer, but it is absolutely necessary to download and add the Cisco IOS for GNS3.
You need to use GNS3 to use the actual Router and Switch IOS images. With this software, you can emulate a Cisco Router/Switch and prepare for Cisco exams in a more professional way.
You can download and use the most suitable Cisco images to avoid problems when using the network simulator. You can also check out this article to install GNS3 on your computer.
You also need to configure Minimum RAM when adding a Cisco Router or Switch images to the program.

If you set a value that is greater than the minimum RAM requirement, you will put more load on your computer’s processor and experience performance issues.
If you have a powerful PC, you can also set a higher RAM value for Cisco Routers.
When adding a Router to the simulator software, an IDLE-PC value is also determined. The IDLE-PC value is determined by the hardware specifications of your computer so that the routers you add can work more efficiently.
The running IOS images you can use on GNS3 are the c3640, c3660, c3725, c3745, and c7200 versions.
Here are a few additional Cisco Router images. For example, if you use a c1700 series Router, it will be insufficient because it does not support some features when you create a more advanced network topology.
