Details of VirtualBox and Containerlab support are described below, for extensive vagrant-libvirt details please refer to the installation guide.

Vagrant with VirtualBox

  • Most networking vendors don’t ship Vagrant boxes, and I had no interest in building VirtualBox boxes from scratch after setting up a libvirt-based lab on an Intel NUC. The only boxes I could get with zero hassle were Cisco Nexus 9300v and Arista vEOS, and they both work fine. If you want to add other devices, you’ll have to modify topology-defaults.yml file.

  • The latest version of Arista vEOS available as Vagrant box for VirtualBox is 4.21.14M.

  • Vagrantfile created by create-topology sets up port forwarding for SSH (22), HTTP (80) and NETCONF (830), but the corresponding Ansible inventory contains only ansible_port (SSH). You could edit the final inventory by hand, add extra file to host_vars, or fix my code. Should you decide to do the latter, please contact me in advance to discuss the necessary data structures.

Containerlab

  • The only devices currently supported are Arista cEOS and FRR

  • Feel free to extend the templates and defaults to support other network devices
