What are QEMU and IOU devices in GNS3? What does Jeremy (GNS3 Creator) recommend we use? Does QEMU only support VIRL? Or are other vendors supported? What about ASA 8.x? Is that supported? #gns3 #virl #iou

David Bombal talks to Jeremy Grossmann (creator of GNS3) about the future of GNS3. Here we discuss Dynamips and VPCS and their future in GNS3. Will they be removed from GNS3? Are they recommended? What do they actually do? What should be used instead of them? Does Dynamips support switching? In future videos we will discuss additional options in gns3 such as Cisco VIRL and IOU. Menu: 0:12 - Devices in GNS3. It can be confusing. What is Dynamips 0:57 - Does GNS3 support switching? 1:17 - Are they real IOS images? 1:47 - Issue 1: Where do I get Cisco images? Cisco restrictions. 2:07 - Issues 2: Only older versions of Cisco IOS are supported on a lot of platforms 2:11 - Is it stable? Issue 3: More memory and processor intensive 2:25 - What is Idle PC Value 4:23 - Advantage 1: Supports serial interfaces 4:50 - Dynamips is a dying product 5:00 - You can run Dynamips locally 5:40 - What does Jeremy recommend we use? 5:50 - Switching in Dynamips? 7:18 - Will Dynamips be removed from GNS3? 7:48 - What is VPCS? 8:28 - What is the advantage of VPCS? 8:55 - Should we be using VPCS? 9:58 - Will VPCS be removed from GNS3?

Is this a replacement for Visio? GNS3 now allows you to create interactive topology diagrams. You can create topologies consisting of both physical and virtual devices and get them to communicate with each other. Will gns3 replace visio? How will you make the most use of this new feature in gns3? #gns3 #visio #ccna
