This is an internal Cisco tool which is so useful – that I am really pleased that it is finally available for public consumption.
VIRL Stands for Virtual Internet Routing Lab
What Is VIRL?
**_VIRL is comprehensive network design and simulation platform. VIRL includes a powerful graphical user interface for network design and simulation control, a configuration engine that can build complete Cisco configuration at the push of a button, Cisco virtual machines running same network operating systems as used in Cisco’s physical routers and switches, all running on top of OpenStack. _**
How Does VIRL Work?
VIRL uses the Linux KVM hypervisor and OpenStack as its virtual machine control layer, with a powerful API enabling the creation and operation of VMs in a simulated network topology. Users design their network using the VM Maestro design and control interface, with network elements such as virtual routers, switches and servers. The design is translated into a set of virtual machines running real Cisco network operating systems.
What Does VIRL Offer?
Design, learn and test with virtual machine running real Cisco network operating systems – IOS, IOS XE, IOS XR and NX-OS as well as virtual machine running 3rd party operating systems. Build highly-accurate models of real-world or future networks, study the behaviour and configuration of routing protocols, break and fix your network and understand how to troubleshoot with a powerful integrated platform.
