Abstract
Message summarization and flood suppression may be provided. A proxy (e.g., an IGMP Proxy) process may be used to reduce the flooding of messages (e.g., IGMP messages) over a network (e.g., an EVPN network). A triggering process may also be provided for provider edge (PE) devices to setup their underlay multicast tunnels. The proxy may comprise two components: i) a proxy for reports (e.g., IGMP reports); and ii) a proxy for queries (e.g., IGMP Queries).
