EVPN Demo running Cumulus VX with Vagrant (KVM and Virtualbox are supported)

Demo EVPN on Cumulus Linux

This Github repository contains the configuration files necessary for setting up EVPN (Ethernet VPN) using Cumulus Linux and Quagga on the Reference Topology. Only Server01->Server04, Leaf01->Leaf04 and Spine01->Spine02 are used.

The flatfiles in this repository will set up a BGP unnumbered routing fabric between the leafs and spines, and will trunks between switches and the servers in that rack.

Quickstart: Run the demo

git clone https://github.com/cumulusnetworks/cldemo-evpn
cd cldemo-evpn
vagrant up oob-mgmt-server oob-mgmt-switch 
vagrant up leaf01 leaf02 leaf03 leaf04 spine01 spine02 server01 server02 server03 server04
vagrant ssh oob-mgmt-server
sudo su - cumulus
ssh server01
ping 172.16.1.104

Requirements

Vagrant

and

VirtualBox or KVM

Factory-reset a device

vagrant destroy -f leaf01
vagrant up leaf01

Destroy the entire topology

vagrant destroy -f

KVM Support

By default this Vagrantfile is setup for Virtualbox. To use this Demo for KVM use the Vagrantfile-kvm

mv Vagrantfile-kvm Vagrantfile

All other directions remain the same

Virtualizing a Network with Cumulus VX

---

Cumulus VX is a virtual machine produced by Cumulus Networks to simulate the user experience of configuring a switch using the Cumulus Linux network operating system. Vagrant is an open source tool for quickly deploying large topologies of virtual machines. Vagrant and Cumulus VX can be used together to build virtual simulations of production networks to validate configurations, develop automation code, and simulate failure scenarios.

Vagrant topologies are described in a Vagrantfile, which is a Ruby program that tells Vagrant which devices to create and how to configure their networks. vagrant up will execute the Vagrantfile and create the reference topology using Virtualbox. It will also use Ansible to configure the out-of-band management network.
