Cisco Live US 2026 (Las Vegas) digest Program Core pick Las Vegas · 31 May – 4 June 2026

Abstract

Lukas Krattiger (Cisco)

  • Why: EVPN/VXLAN datapath internals are a core interest — this is the "follow the packet" internals session, not a feature overview.
  • What: A day-in-the-life walkthrough of a VXLAN EVPN packet: routing and bridging behavior, and multi-destination (BUM) traffic handling, from ingress VTEP to egress VTEP and beyond (from abstract only).
  • How: Step-by-step datapath trace of encap/decap, ARP suppression, and multicast replication mechanics on the fabric.
  • Where applicable: Any VXLAN EVPN fabric; mechanism-focused rather than product-specific.
