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).

Abstract: Aspects of the embodiments are directed to synchronizing at least a portion of a link-state database. A network element can lose an adjacency. The network element can transmit a request to a neighboring network element for synchronization of a link-state database. The request can include a version number of a last synchronized link-state database from the neighboring network element. The neighboring network element can determine whether the version of the link-state database is greater than or less than a copy of the link-state database stored by the neighboring network element. If the requested version number is less than the neighboring network element's link-state database version number, then the neighboring network element can send changes to the link-state database since the requested link-state database version number.
