At the beginning of 2021, namex ixp has started the rollout of its next-generation peering platform, the active infrastructure which is at the core of its network interconnection facility. This new platform relies on an IP fabric design with vxlan as the overlay network and BGP evpn as the control plane protocol. The development of this project started back in March 2020 and saw Mellanox and Cumulus Networks (both parts of NVIDIA corporation now) as major technological partners.
Before diving into the details, a brief historical note may help to understand the drivers and motivations behind such technical choices.
