VXLAN BGP EVPN Multi-Site - BRKDCN-2913#
Cisco Live Europe 2025 (Amsterdam) digest Program Core pick Amsterdam · 9–14 February 2025
Speakers: Lukas Krattiger (Cisco)
- Why: DC-to-DC interconnect is core to the PM's remit; this is the canonical session on how Cisco thinks separate EVPN fabrics should be stitched together, and where the approach is heading.
- What: The evolution of Cisco's approaches for interconnecting separate VXLAN BGP EVPN fabrics — from multi-pod to multi-fabric to the current VXLAN multi-site design, positioned as the recommended interconnect for discrete EVPN islands. (from abstract only)
- How: Uses the VXLAN data plane with EVPN as control plane across sites — typically via a DCI overlay where EVPN routes leak between sites with scoped route targets and designated-forwarder election extended across sites, aiming for L2 extension plus integrated L3 without full-mesh state.
- Where applicable: Explicitly NX-OS standalone VXLAN EVPN only — it excludes ACI's multi-pod/multi-site solutions, so multi-vendor or ACI shops get design philosophy rather than recipes. The general multi-site EVPN patterns are broadly applicable.
