Technical Summary

   This document describes the EVPN Proxy-ARP/ND function, augmented by
   the capability of the ARP/ND Extended Community.  Together, these
   help operators of Internet Exchange Points (IXPs), Data Centers
   (DCs), and other networks deal with IPv4 and IPv6 address resolution
   issues associated with large Broadcast Domains (DBs) by reducing and
   even suppressing the flooding produced by address resolution in the
   EVPN network.

Working Group Summary

   The document was developed to address the desire to minimise flooding of traffic 
   associated with address resolution in EVPN. It is particularly important due to the
   large size that EVPN networks can grow to, particularly in terms of the numbers of CEs 
   and hosts. It makes recommendations for implementations of Proxy-ARP/ND to help 
   operators deal with the issues derived from Address Resolution in large broadcast
