Cisco Live US 2025 (San Diego) digest Program Core pick San Diego · 8–12 June 2025

Abstract

Lukas Krattiger (Cisco)

  • Why: "A day in the life of a packet" is exactly the datapath-internals treatment the PM values — most EVPN content covers control plane; this follows the data plane.
  • What: How routing and bridging actually happen across a VXLAN EVPN fabric — what occurs from the ingress VTEP through to the egress VTEP and beyond, including how multi-destination traffic is handled (from abstract only).
  • How: Step-by-step packet walk through the overlay, ingress to egress.
  • Where applicable: The mechanics are general to VXLAN EVPN regardless of vendor; examples will be NX-OS-based.
