Demo L3 VRF-lite Tenant Isolation on Cumulus Linux

This Github repository contains the configuration files necessary for setting up a VRF-lite infrastructure using Cumulus Linux and Quagga on the Reference Topology. Only Server01->Server04, Leaf01->Leaf04 and Spine01->Spine02 are used.

Ansible is the mechanism which is used to deploy the VRF configuration onto all components. As a result, this demo depends on cldemo-vagrant to run.

Quickstart: Run the demo

git clone https://github.com/CumulusNetworks/cldemo-vagrant
cd cldemo-vagrant
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
git clone https://github.com/rdarbha/vrf-demo-ansible
cd vrf-demo-ansible
ansible-playbook deploy_network.yml
ssh leaf01
sudo vtysh -c "show ip route vrf all"

Requirements

Vagrant

and

VirtualBox or KVM

Instructions in installing virtualization software

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.
