README.md

This repository is a library of examples/demo using Vagrant and vqfx10K. Each example has its own directory and will contain at least a Vagrantfile

Launch vqfx10k

Once you have followed the installation procedure, you can start a topology with few lines

To try an example, you just have to go inside a specific directory and run "vagrant up":

git clone https://github.com/Juniper/vqfx10k-vagrant.git
cd vqfx10k-vagrant/light-2qfx
vagrant up

Some topologies are using Ansible, If you don't have ansible you can start them using vagrant up --no-provision

Once both VMs are up and running, you can connect to them with:

vagrant ssh vqfx1
vagrant ssh vqfx2

Available examples:

vQFX10K

vqfx10k is a tool provided for lab and training; this is not a intended to be used in production. Capacities are similar to a real QFX10K but performance are very limited in this version, few 100s PPS.

Mode, Architecture and Limitations

vqfx10k for Vagrant can work in 2 modes: Full and Light

Full Mode

In Full mode, it require 2 VMs for each instance:

  • 1 Routing Engine VM, running Junos (vqfx10k-re-virtualbox-##.box)
  • 1 Packet Forwarding Engine, running Linux (vqfx10k-pfe-virtualbox-##.box)

In Full mode, the dataplane is fully functional and is very close to the real QFX10K

These 2 VMs need to be interconnected with a dedicated private network on their interface number 1, (interface 0 is always reserved for Vagrant for management). All data plane interfaces need to be connected to the Routing Engine (RE) VM. Up to 12 data plane interfaces are supported. Port names will be xe-0/0/0 to xe-0/0/11.

Full Mode Limitations

Only few features are not supported due to some architecture differences between vQFX10K and a real QFX10K

Unsupported features:

  • Analytics
  • Guest VM/ Guest container

Light Mode

In Light mode, only 1 Routing Engine VM, running Junos is required for each instance.
Up to 5 interfaces are supported to connect to external devices. Interface names will be em3 to em7

Light Mode Limitations

In Light mode, most data plane features are not supported and all packets are processed in kernel

Family ethernet-switching is not supported in light mode

VM Characteristics

vqfx10k-re

Requires:

  • 1GB of memory
  • Interfaces type must be type: 82540EM

A maximum of 12 interfaces are supported:

  • first interface is used by vagrant (em0)
  • second interface is used to connect to the PFE VM (em1)
  • third interface is a management port not used (em2)
  • All remaining interfaces can be used to connected to other devices

This VM has 2 account by default:

  • login: vagrant, with ssh_key authentication using vagrant insecure_key
  • login: root, password: Juniper

Virtualbox only support 8 interfaces by default

vqfx10k-pfe

Requires:

  • 1.5/2GB of memory
  • 1 dedicated core

A maximum of 2 interfaces are supported:

  • first interface is used by vagrant (eth0)
  • second interface is used to connect to the RE VM (eth1)

This VM has 2 account by default:

  • login: vagrant, with ssh_key authentication using vagrant insecure_key
  • login: root, password: no

Vagrant

What is Vagrant Vagrant is an open-source (MIT) tool for building and managing virtualized development environments developed by Mitchell Hashimoto and John Bender. Vagrant is able to create VMs, connect them together and is specify configure them automatically.
Here is a good introduction to Vagrant for Network Engineer

Providers

For now, only VirtualBox is supported as a provider.

VMware will be added later.
