Internet Group Management Protocol (IGMP) / Multicast Listener Discovery (MLD)-Based Multicast Forwarding ("IGMP/MLD Proxying")

Status of This Memo This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited. Abstract In certain topologies, it is not necessary to run a multicast routing protocol. It is sufficient for a device to learn and proxy group membership information and simply forward multicast packets based upon that information. This document describes a mechanism for forwarding based solely upon Internet Group Management Protocol (IGMP) or Multicast Listener Discovery (MLD) membership information.
