VXLAN EVPN: A Deep Dive into Packet Forwarding - BRKDCN-3966#

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

Abstract

Lukas Krattiger (Cisco)

  • Why: EVPN is the dominant DC overlay control plane and datapath-debugging knowledge is where most operational pain lives. This is a datapath-internals talk, not an EVPN primer.
  • What: A packet-by-packet walkthrough of VXLAN EVPN forwarding — routing, bridging, and multi-destination handling from ingress VTEP through to egress VTEP and beyond (from abstract only).
  • How: "Day in the life of a packet" structure following a concrete frame through the overlay.
  • Where applicable: Any VXLAN EVPN fabric (Nexus 9K baseline is Cisco's, but the mechanics are standard). Assumes working EVPN knowledge.
