                      IGMP and MLD Proxy for EVPN
                draft-ietf-bess-evpn-igmp-mld-proxy-03 

Abstract

   Ethernet Virtual Private Network (EVPN) solution [RFC 7432] is
   becoming pervasive in data center (DC) applications for Network
   Virtualization Overlay (NVO) and DC interconnect (DCI) services, and
   in service provider (SP) applications for next generation virtual
   private LAN services. 

   This draft describes how to support efficiently endpoints running
   IGMP for the above services over an EVPN network by incorporating
   IGMP proxy procedures on EVPN PEs.
