IGMP and MLD Proxy for EVPN
draft-ietf-bess-evpn-igmp-mld-proxy-04
Abstract
Ethernet Virtual Private Network (EVPN) solution 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.
