Cisco’s Virtual Internet Routing Lab (VIRL) is a network simulation tool developed by Cisco that allows engineers, certification candidates and network architects to create their own Cisco Lab using the latest Cisco IOS devices such as Routers, Catalyst or Nexus switches, ASA Firewall appliances and more.
Being a fairly new but extremely promising product it’s quickly becoming the standard tool for Cisco Lab simulations. Managing and operating Cisco VIRL might have its challenges, especially for those new to the virtualization world, but one of the biggest problems has been the lack of dedicated online resources for VIRL management leaving a lot of unanswered questions on how to use VIRL for different types of simulations, how to build topologies, how to fine tune them etc.
The recent publication of “The VIRL Book’ by Jack Wang has changed the game for VIRL users. Tasks outlined above plus a lot more are now becoming easier to handle, helping users manage their VIRL server in an effective and easy to understand way.
