Add it to a lab

In Add Node, choose the template, then the image. The template fills in these settings; change them before you start the node.

EVE-NG admits a node by the CPU and RAM set on it, so a running node counts against your plan at these values. This template starts nodes at 1 vCPU and 512 MB, which fits the free demo’s 6 vCPU and 8 GB, so you can start one there and open its console.

Dual-homed BGP with four VyOS routers

Run iBGP between two VyOS routers at your site and eBGP from each to its own ISP router, also VyOS, with an Alpine Linux host on the site LAN. You practise BGP sessions, local preference and route maps.

  • 4×VyOS vyos1 vCPU, 512 MB each
  • 1×Alpine Linux clbalpinebase2 vCPU, 512 MB

Added with these defaults, the lab uses 6 vCPU and 2.5 GB of RAM. The smallest plan that fits is Lite, with 6 vCPU and 8 GB: £3 a day, or £0.50 an hour On-Demand.

Choose a planGive nodes more CPU or RAM and you add that instead.

Licences are yours to bring

VyOS is open-source software, so a router lab needs no licence key. CloudLabBox doesn't provide VyOS subscriptions.

The images run only inside your CloudLabBox workspace; they aren’t available to download.

Questions about VyOS

What is VyOS?

VyOS is an open-source router and firewall built on Debian, with a commit-based configuration CLI. Its routing protocols run on FRRouting.

What are a VyOS node's interfaces called?

EVE-NG labels them eth0 to eth3, the same names VyOS gives its Ethernet interfaces.

Which VyOS commands apply and keep my configuration?

commit applies your changes and save writes them to the boot configuration. Run both before you stop the node.

VyOS: which image reached its login prompt?

vyos-1.3.1-amd64 reached its login prompt. Configure the interface addresses and routes for your topology, then save the guest configuration before stopping the node.

From the node tips, updated 9 October 2026.

Which VyOS images are installed?

11 images, all listed on this page exactly as Add Node shows them. The newest is vyos-1.5-rolling-amd64.

How much CPU and RAM does a VyOS node use?

When you add one, the vyos template adds 1 vCPU and 512 MB of RAM. You can change both in Add Node, and your plan counts what each running node is set to.
