VIRL (Virtual Internet Routing Lab)
Hi ! everyone today we are going to learn about VIRL. Now we can proceed to the detailed explanation which is shown below.
What do you know about VIRL ?
VIRL (Virtual Internet Routing Lab) is Cisco's powerful network simulation platform, with Cisco OS virtual machines shipped with the software package - It's your flexible, all-in-one virtual networking lab. No more bulky network equipment and hours of wiring! Easy-to-build connections to actual networking equipment to expand or extend your lab by linking physical and virtual networking devices.
When we say that network orchestration means it is largely an effect of automation or systems deploying elements of control in form of theory. This usage of orchestration is often used to discuss in the context of service-oriented architecture, virtualization, converged infrastructure and dynamic data center topics. As we could see that the virtualization has already mentioned above that it is the platform that provides these details given below:
- Point-and-click network design
- Automated configuration creation
- Virtual Machines running Cisco operating system
- IOS, IOS Layer-2 switching
- IOS XE, IOS XR
- NXOS, ASA (Adaptive Security Appliances)
- Rapid setup and tear-down
- Seamless connectivity with real networks
- Portability and repeatability
- To create new network services and solutions.
- To learn and test new features and functions.
- To be more innovative to solve business problems.
GOAL TO SUCCESS
The goal of this Learning Lab is to help you to develop in a basic level of proficiency using VM Maestro and VIRL. Once you are familiar with VIRL you'll be able to use it to efficiently create networks, test configurations, explore features, and build test beds against which you can develop and test SDN facilities such as APIs, programmatic interfaces, and controllers.
15 Reasons we should learn in VIRL are:
- VIRL supports an ever-widening list of Cisco device images and features, making the product ideal study tool for a growing list of certifications and networking paths.
- VIRL provides advanced features not found elsewhere. For example, Auto Net Kit permits the automation of bad configurations, while the Live Visualization feature permits views of your working topology like no product before it.
- VIRL allows for easy-to-build connections to actual networking equipment, making it an excellent testing platform for production deployments.
- VIRL is a completely legal and licensed solution. No more searching virus-filled web downloads for the components you need to emulate Cisco networking equipment.
- VIRL is consistently improved and updated with new features, new images, etc, that all are delivered via a convenient online upgrading process.
- VIRL which comes with a complete set of legal and licensed Cisco IOS images that are the same as those running on physical routers.
- VIRL has better view of images and advanced functions when we compare with others lab simulations like packet tracer, GNS3,etc.
- VIRL runs on most of the computers which has some minimum hardware requirements in this is an Intel-based computer with four “logical” CPU cores (not physical CPU's), 8 GB of RAM and 70 GB free disk space.
- VIRL suggests larger memory, such as 12 GB for 20 nodes, 15 GB for 30 nodes, (or) 18 GB for 40 nodes. Each Cisco IOS-XRv node requires 3 GB of memory to launch.
- VIRL has flexible installation options to install a VIRL on these particular, enterprise-grade server infrastructure, a desktop computer, a laptop, or even on the cloud. You can run it as a Virtual Machine on VMware ESXi, VMware Workstation, Player or VMware Fusion for Mac OS, etc.
- VIRL has automatic configuration which can assign IP addresses to the nodes automatically when they have launched and it can set basic routing protocol for us.
- VIRL has great features for network engineers who want to setup a one-time temporary environments to look up command and test some main features.
- VIRL should have Intel VT-x / EPT or AMD-V / RVI virtualization extensions present and enabled in the BIOS.
- VIRL is great at building labs with up to 15 devices; anything more than that, and you’re forced to start incorporating physical devices.
- VIRL have been extending your virtual lab into real world, without those devices even realizing that they are talking to virtual hardware through this VIRL.
Node Types that we should know basics before moving into VIRL
ROUTERS Descriptions
IOSv It is a lightweight router that supports everything in CCNA/CCNP needs.
CSR1000v It is a heavyweight IOS-XE router that is suited for CCIE studies.
IOS XRv It is a Service Provider IOS-XR router that is suited for the Cisco Service Provider.
SWITCHES Descriptions
Unmanaged Switch A virtual switch similar to GNS3 virtual switch and provides connection between devices.
IOSvL2 A IOS switch that supports a good views with CCNA/CCNP/CCIE switching features that you would want.
NX-OSv A Nexus switch that supports Layer-2 and Layer-3 features and some of Nexus specific features.
About VIRL on Packet
This VIRL Packet provides us a wide variety of bare-metal server and VMware it is also a computer software like this VIRL packet. VIRL requires an AMD64 architecture. Second, some Packet servers provide hardware that is just not applicable or used by VIRL, so there’s no need to pay for it. We recommend Type-0, Type-1, Type-1E, and Type-2 servers:
Cisco provides a resource calculator that you can use to size a system based on your needs, but in general customers use:
- Type-0 for simulations of up to 12 nodes of IOSv. (Education)
- Types-1/1E for larger simulations of 10 to 30 nodes including a mix of IOSv, servers, and a few of the the ‘heavier’ operating systems like IOS XRv, CSR1000v, an NX-OSv. (Small-scale professional use).
- Type-2 for up to 40 nodes including a mix that is skewed towards the heavier operating systems. (Large-scale professional use).
Therefore, we have understood some basic knowledge about Cisco VIRL Packet.
