Test Network
The test network is comprised of two virtual machines running VyOS, with a single interface connected to a shared broadcast domain. On this interface, there are VLANs for subnets which will be shared using BGP, plus site-to-site VPN links. Both VMs will be administered using a serial console, so there is no need to have any management machine, but optionally a client can be attached to the broadcast domain and even tagged with a VLAN if necessary.
Rather than using hardware, I will be running this virtual network on my at-home hypervisor, which runs Proxmox, and currently has an internal bridge interface configured, which the routers are connected to.
The IP addresses are assigned as follows:
