Cisco Live Europe 2026 (Amsterdam) digest Program Core pick Amsterdam · 9–13 February 2026

Abstract

Frederic Cuiller (Cisco), Elise VENNEGUES (Netflix)

  • Why: A joint operator/vendor case study on BGP route-reflector architecture at global scale — BGP internals plus the messy realities of validation and migration, told by the operator themselves.
  • What: How Netflix and Cisco evolved Netflix's BGP architecture around the IOS XRv9000 on a UCS M7 appliance, developed and refined against Netflix's requirements: motivations, design, validation, deployment, and migration strategy with lessons learned (from abstract only).
  • How: Design-and-migrate narrative: technical challenges, collaborative development, validation and best practices for a seamless transition from the previous route-reflector setup.
  • Where applicable: Netflix-specific in scale and requirements, but the route-reflector appliance pattern and migration methodology generalize to any large SP or edge network. Expect concrete only if the speakers go deep on validation data.
