The ZTVI Network is the circulatory system of our organization. ZTVINet operates as an international backbone and is a 100% overlay network, meaning, there are almost no physical assets other than the virtual routers and VMs necessary to connect to the physical internet. We currently operate as AS19625 and have been allocated 2602:fc59::/40 and 23.188.240.0/24 in the ARIN region. ZTVI operates as an almost 100% IPv6-only network. We currently only utilize IPv4 for out of band management, NAT64, and occasionally on a PNI with no peering in some locations. Legacy IPv4 exists as an “as a service” overlay (IPv4aaS).

Our current peering locations are:

  • ABQIX; Albuquerque, NM, US
  • VULTR DC; Chicago, IL, US
  • ZTVI CU; Champaign, IL, US
  • VULTR DC, Sydney, AU
  • Hurricane Electric Fremont 2, CA, US

Peering node requirements:

Space for a small linux system (or provided system or VM) capable of ingesting a full IPv6 DFZ. Our network is run primarily on Ubuntu Linux systems using FRR, although we are open to any platform that is able to meet our requirements.

Network Requirements:

  • Support for IPv6-Only
  • IS-IS
  • MP-BGP
  • ZeroTier
  • 1G physical or virtual interface (VMs are fine, 2-3 interfaces desirable but not required)
  • An IPv6 BGP peering
  • In the future we plan to implement SR-MPLS and / or SRv6, but these are not current requirements.

Our network is built to operate as a carrier backbone, connect customer edge devices (generally a smaller version of what we use as a “provider edge router” - an rpi4 is commonly used).

How is this thing managed?

Right now this network is primarily managed with Ansible. This is a best-effort, experimental endeavor. We don’t want to spend time hand crafting artisanal network elements any more than we already do. Anything that is repeated more than a few times is automated. We use NetBox as a DCM and IPAM.

What ZTVI isn’t:

  • A high throughput broadband service.
  • A public TunnelBroker (use the HE tunnelbroker until you can convince your ISP to provide it natively).
  • A mechanism for streaming outside of your region.
  • A network with no rules.
