IGMP and MLD Proxy for EVPN
draft-ietf-bess-evpn-igmp-mld-proxy-02
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.
