Cisco VIRL vs. GNS3 How They Compare. Cisco VIRL is in the wild and there are some good and bad things about it. Lets jump right into some of the features with a comparison between VIRL and GNS3. Also, in no way is this intended to be a complete comparison, rather its just a gathering of my thoughts between the two. The Legality of it all. GNS3 requires that you obtain Cisco IOS on your own. This grey area may violate the Cisco IOS terms of use, which might deter some from using GNS3. VIRL on the other hand, licenses the use of Cisco IOS. Ease of Use. VIRL is a pain to setup. It seems like you have to just through a ton of hoops. NTP sync, License server, interface setups, and so on. Aside from adding IOS, GNS3 is pretty easy. There are some extenuating circumstances where you would add loopbacks or tap interfaces but thats a little more advanced than the functionality the two products have from the get go. Where Are the Serial Interfaces First thing that stands out is serial interface support. GNS3 Graphical Network SimulatorCisco IOSCiscoCisco IOS. A list of eleven opensource network simulators that run on Linux or FreeBSD systems, and use opensource router software. Free Cisco Lab Simulators GNS3 Graphical Network Simulator. GNS3 is a graphical network simulator that allows simulation of complex networks. GNS3 How to download Cisco IOS images and VIRL images. Which is the best How do you get them Cisco IOS images for Dynamips. GNS3 offers multiple ways to emulate IOS. For older images, we use and maintain Dynamips an emulator dedicated to emulate some Cisco. Learn how to configure Cisco ASA 8. GNS3. Download compatible Cisco ASA 8. VIRL doesnt support serial interfaces, but Serial interfaces are a possible option for future releases. The inability to support Serial interfaces right now is a major downfall to CCIE candidates. GNS3 has support for serial interfaces. Baixar A Bolsa Amarela Pdf on this page. Additional Device Support. VIRL supports IOS XR, IOS XE, NX OS, and Classic IOS. VIRL ties to a flat network which allows you to bridge to other machines skys the limit. GNS3 supports IOS, and a number of other flavors of things. It has an internal Frame Relay switch, ATM switch, L2 switch, hubs, clouds to bridge to VMs and physical networks, IOU, Virtual Box, and QEMU integration. It seems to be a bit more weighted toward GNS3 in this case, but because of virtualization capabilities I think its a close one. The downside I would say of VIRL is that the VMs would be created separately and added to your topology through the Flat network. So, really that is a limitation so this round goes to GNS3. Vendor Support. There are a few vendors who are packaging or allowing the packaging of their products into the install of GNS3.

Requirements to configure Cisco IOU on GNS3 1. Cisco IOU IOS on UNIX. Cisco VIRL is in the wild and there are some good and bad things about it. Lets jump right into some of the features with a comparison between VIRL and GNS3. The Cisco IOS XE Release 3. Kernel Based Virtual Machine hypervisor. Thanks to the this awesome enhancement, Cisco CSR 1000v running IOS XE 3. Solarwinds Response Time Viewer is packaged into GNS3 along with a free download of NCM. There are tutorials on how to get Arista integrated with GNS3. Wireshark is packaged in the install to capture on any interface a HUGE plus for learning. VIRL doesnt advertise integration with anyone, although it might be possible. GNS3 wins again. OOB Access. Both VIRL and GNS3 support OOB access to the CLI. It seems that its a little easier to do in GNS3, but alas, they both support it. This ones a tie so Ill give them both a mark Auto Configuration of Interfaces and Routing Protocols. Heres something GNS3 doesnt do With Auto. Net. Kit VIRL can spin up a topology with IPv. IPv. 6 addresses, routing protocols and all. Cost. Yep Cisco charges almost 2. VIRL and GNS3 is free. GNS3 did do a crowdfunding campaign a while back and many people contributed, so there was some financial backing behind the current release, but Im sure its nowhere near what Cisco has available. And the Winner IsWell for now I think the ease of use and extent of capabilities goes to GNS3, however I dont think this will be true long term, provided Cisco takes the product seriously and continues to get BU buy in and additional support. GNS3 is a much more mature product and while it has a strong community backing, it doesnt have an all access pass to everything Cisco. If Cisco integrates more products directly into the VIRL interface such as ASA, IPS, WLC, IP Phones and so on, it could be the Gold Standard in study tools. For now I think there is some initial interest in VIRL since its new and shiny, but some who purchase it will likely struggle and give up for a while, going back to their familiar GNS3. So, Im not bashing VIRL at all here, and I recommend you grab it and take it for a spin if you have the means to do so. There are of course other areas to be considered, but as mentioned in the onset of this article, its not intended to be a complete comparison. I just touched on a few areas here that I immediately noticed. So todays winner is.
