Modern Multi-Homing in VXLAN EVPN: Enabling vPC and ESI+ in Today's Data Centers - BRKDCN-2940#

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

Abstract

Parth Patel (Cisco)

  • Why: EVPN ESI multihoming landing in NX-OS 10.6.1 is a real control-plane shift for Cisco fabrics; the vPC-vs-ESI trade-off is a live design decision.
  • What: A comparison of classic vPC and the new EVPN ESI multihoming (ESI+), covering how each works, what changes with ESI+, and when to choose one over the other (from abstract only).
  • How: Real design examples and packet-flow comparisons, framed around fabric scale, resiliency requirements, and operational model. Assumes prior vPC-VTEP knowledge.
  • Where applicable: NX-OS fabrics specifically; the ESI-MH model itself is the IETF standard mechanism also used by other vendors and SONiC, so the concepts travel well.
