Building Scalable AI Cloud Interconnects with SRv6
summary
Nebius uses SRv6 to replace VXLAN/MPLS stitching and run a single IPv6 routed fabric that delivers end-to-end VPN and Traffic Engineering without protocol translation, supporting multi-tenant L2 VPNs and firewall service chains. Implementation uses SRv6 micro-sid to keep packet overhead low and a custom VPP cloud gateway on hosts. Production tests show vendor interoperability and the ability to carry customer flows at hundreds of gigabits and into multi‑terabit ranges while eliminating VRF stitching and central translation bottlenecks.
