What is VIRL?

© 2017 Cisco and/or its affiliates. All rights reserved. Cisco Public

Virtual Internet Routing Lab

A network orchestration and virtualization platform that allows you to:

• Design graphically

• Configure automatically

• Visualize and validate

• Interact like it’s real

• Connect to live networks

• Integrate into DevOps

DEVNET-1172 5


Why Should You Care?

• Because you’re a student or teacher, network operator, engineer, or application developer

• And you need a test or development environment that is:

Easy to use

Easy to configure

Easy to scale

Repeatable

Easy to access

Portable

Inexpensive

VIRL Architecture and Operations


VIRL System Architecture

Virtualized network platforms

• IOSv / v-L2

• IOS XRv / 9000v

• NX-OSv / 9000v

• CSR1000v

• Generators

• ASAv

• Servers

• LXCs

• Docker

• 3rd-Pary Appliances

Virtualized platforms are NOT representations of a particular hardware

platform – no fans, no switch fabric, no ASIC models `

DEVNET-1172 10


VM Maestro

• The graphical front-end for VIRL

• Design and configure networks

• Manage simulations

• Connect with consoles

DEVNET-1172 11


Browser-Based Editor

• HTML5-based topology editor

• Runs on the server –nothing on client

• Substantial subset of VM Maestro

DEVNET-1172 12


AutoNetkit

• Has deep platform and network intelligence

• Builds baseline configurations

• Generates detailed visualizations of protocol layers

• Enables rapid assessment and debugging

DEVNET-1172 13


VIRL Topologies

• Stored as XML

• Human readable

• Editable

• Automatable

• Shareable

DEVNET-1172 14


Services Topology Director

• Simulation orchestration and management

• Uses OpenStack to simulate what you build

• Exposes operational data for simulations

15DEVNET-1172


User Workspace Manager

• Server configuration

• Simulation status

• Browser-based editor

• Users

• Images

• Networks

Once Up and Running


See Status Instantly

• Active Canvas

• Get live status of nodes and links

• Access node and link properties

19DEVNET-1172


Access and Configure

• Out-of-band via console, LXC

• In-band via private or shared networks

• Access via VM Maestro, host, or remote

20DEVNET-1172


Start, Stop, and Pace Nodes

21DEVNET-1172


Simulate Link / Interface Failures

22DEVNET-1172


Simulate Real-World Conditions

• Add latency

• Insert jitter

• Drop packets

23DEVNET-1172


Configuration Extraction

• Make live changes

• Pull them back

• Save with your topology

• Resume where you left off

24DEVNET-1172


Live Visualizations

• View live protocol state

• Reacts in real-time

• Many protocol layers

25DEVNET-1172

VIRL Demonstration

Key VIRL Use-Cases


Self-Education / Certification Training

28DEVNET-1172


Instructor-Led Training

Low-cost, efficient infrastructure

Access to ‘exotic’ systems

Portable and repeatable

29DEVNET-1172


Demonstrations

30DEVNET-1172


New Feature / Solution Evaluation

Will these new features work in my network?

How are they configured?

31DEVNET-1172


Troubleshooting

Why did that new route-map send all traffic to Houston?

Why aren’t our multicast groups being learned?

32DEVNET-1172


DevOps Automation Testing

APIs + Tests

Code

Triggers

Results

33DEVNET-1172


Scale and Integration Testing

Test new systems in your network...

Without touching your real network

34DEVNET-1172


Skills Validation

Am I really ready for this test?

Does the candidate have the skills I need, and claim to have?

35DEVNET-1172


Familiarization

How can you best teach her the nuances of your network?
