A Network Virtualization Overlay Solution using EVPN
summary
An EVPN-based network virtualization overlay that uses BGP to distribute MAC/IP bindings so endpoints learn remote locations before traffic arrives, avoiding ARP storms and migration cutover loss. The proposal (draft-ietf-bess-evpn-overlay-07) and implementations reference Cumulus switches and the Bagpipe project (now merged into OpenStack components). A demo-level claim is live migrating containers across data centers without packet loss by propagating reachability state in real time; the draft is a work in progress but some switch vendors already ship parts of the solution.
