Standard BGP best-path selection retains only one route per NLRI key, which can suppress reachability information needed for EVPN aliasing, fast convergence, and split-horizon filtering. This document specifies that BGP speakers MUST treat EAD routes as multipath and MUST advertise and install all valid EAD routes for a given Ethernet Segment, rather than selecting a single best path.
