Here I am listing all the working versions of Cisco IOS which I have tested with the latest version of GNS3. Feel free to download them and use them for your Cisco certifications studies. • 1700 – • 2600 – • 2691 – • 3640 – • 3660 – • 3725 – • 3745 – • 7200 (v15) – • 7200p (v15) – Mirror Links: 1. 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.

Hello Srijit, I’ve been having a hard time using the 7200 image (c7200-advipservicesk9-mz.152-4.S5.bin) in GNS3, and getting my laptop to find a valid Idle PC value. I’ve even tried to download the image for the 7200 from the link you’ve provided above #8. Still getting the message “0xa000 is not a valid Idle PC value”. The only other 7200 image I’ve used and gotten a valid PC value is c7200-jk9s-mz.124-13b.bin, but when using that image, I’m getting some odd results when configuring various things such as GRE tunnels. Can you assist me with this?
Hello Sir, I have downloaded the image for 7200. Dear Manica, Can you try the steps: 1) change directory to flash: cd flash: Rack1SW3#cd flash: Rack1SW3#dir 2) erase flash: Rack1SW3#erase flash: Erasing the flash filesystem will remove all files! [confirm] Erasing device eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee erased Erase of flash: complete 3) Squeeze flash: Rack1SW3#squeeze flash: Squeeze operation may take a while. [confirm] Squeeze of flash complete Rack1SW3# 4) Try to create vlan again Rack1SW3(config)#vlan 3 Rack1SW3(config-vlan)#exit Rack1SW3(config)#int vlan 3 Rack1SW3(config-if)# To me, resolve my problem.
