In addition to identifying an appropriate sandbox, be sure to provide instructions and any configuration necessary to run your code with the sandbox. DevNet SandboxĪ great way to make your repo easy for others to use is to provide a link to a DevNet Sandbox that provides a network or other resources required to use this code. Be sure to look at the requirements for any given lab topology. Note: Sample Lab Topologies from this repository may leverage nodes that are NOT included with the standard reference platform for CML. Within this repository users of CML can find, or share, network topologies that have been created to highlight a specific type of simulation challenge.

Note: You will need to download the disk images from the vendors yourself.ĬML includes a series of Sample Labs that are available from the Tools menu in Lab Manager, however these are just a start of the possible network simulations that can be created.

A base image definition will reference a node definition. Within each platform folder you will find a YAML file that references a specific disk_image file for a platform.

virl-base-images - Folder containing a folder for each added platform disk image.

The YAML file includes details on how the VM would be configured (ie CPU, RAM, Network Adapters, etc).

node-definitions - Folder containing YAML file definitions for a CML node.

The folder structure of this repository reflect the folder structure and naming conventions used on the CML server itself for storing the definitions.

While we cannot share the actual QCOW image files for nodes that require proper licensing and rights from individual platform owners, we can post the CML YAML file definitions that have been created to support different platforms from Cisco as well as third party vendors. However, CML allows a 'bring your own image' model for any KVM supported image. Included with CML is a library of 'reference platforms' for a variety of Cisco network devices as well as images for Linux servers, traffic generators, unmanaged devices, etc. Examples of this content include: Node and Image Definition Files

This repository is intended to be a place for the CML community to find and share content that builds on top of the standard CML installation. It supports virtual machine based devices using QCOW or KVM format, and can be tied into physical components by 'bridging' the simulation to the real world.

I also show you how to add Docker containers to your network.Community Contributed Content and Resources for Cisco Modeling LabsĬisco Modeling Labs (CML) is a network simulation platform from Cisco that allows for the creation of robust network topologies made up of nearly anything you can imagine. How do you build Cisco networks in GNS3? In this video I show you how to download Cisco IOS images (Cisco VIRL images) to run IOSv and IOSvL2 in your GNS3 topologies.
