Internet Group Management Protocol (IGMP) / Multicast Listener Discovery (MLD)-Based Multicast Forwarding ("IGMP/MLD Proxying")
|Publication Date:||1 August 2006|
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.
