This torrent should have almost ever image you need for emulating Cisco equipment in GNS3 or other emulation software. It has a lot of the images you'll find scattered through a few other prevalent torrents however there are three specifically in here that required lots of effort on my end to find. They are..... -------------------------------------------------------- i86bi_linux_l2-adventerprisek9-ms.nov3_2015_high_iron This is a Layer 2 IOU images. At the time of writing it is considered one of the best if not the best L2 IOU image. I personally just changed the file extension from ".nov3_2015_high_iron" to ".bin" and imported it into GNS3 but apparently there are other ways to do this too. -------------------------------------------------------- vios_l2-adventerprisek9-m-15.2-2017032.qcow2 This is the current VIRL L2 image (again at the time of writing). It's regarded as the best L2 VIRL image. -------------------------------------------------------- nxosv-final.7.0.3.I7.2.qcow2 This is a VIRL image for the Nexus 9000 series. -------------------------------------------------------- If you're new to IOU images DON'T FORGET THAT YOU'LL NEED TO SETUP LICENSING FOR THEM! The keygen.py file in the scripts folder will do that. Google around if you're not sure how to go through this process. ENJOY AND HAPPY LABBING/STUDYING!!!
