    How to install VyOS on Scaleway virtual instance.

VyOS

VyOS is an open source network operating system based on Debian GNU/Linux. It provides a free routing platform that competes directly with other commercially available solutions from well known network providers.[W]
The entire configuration is managed through a CLI that mimic the JunOS cli behaviour. (And I really like that :)
It embeds tons of network features. Most useful with a scaleway deployment will probably be :

VPN: Ipsec, Wireguard, Openvpn..
Routing protocols: BGP, OSPF..

    Howto use vyos openvpn client with scaleway openvpn server

In this howto, I will set up a VPN between a vyos gateway and an openvpn server hosted by a scaleway openvpn instance.
The purpose of this is to hide my entire network behind a scaleway ip address.
Scaleway openvpn instance

Launch an openvpn on a C1 instance with a public ip address.
Openvpn server certificates will take some time to be fully generated. We can check that with scw-ovpn status:
# scw-ovpn status

                BGP ECMP Load Balancer
              
          
    How to build a load balancer with BGP and ECMP using VyOS

According to this cloudflare blog article "Load Balancing without Load Balancers", we can build a rock-solid load balancer only using a router. All the magic comes from BGP and Equal-Cost Multi-Path routing.
In this howto, I will use bird as BGP router on linux instance (ie. servers).
Test environment

I use GNS3 with this architecture :
