Forwarding method and device for multicast messages in SPBM (Shortest Path Bridging Virtual Local Area Network Mode) network

摘要: The invention provides a forwarding method and device for multicast messages in an SPBM (Shortest Path Bridging Virtual Local Area Network Mode) network. comprises the steps that BEB (Backbone Edge Bridge) monitors protocol message through user side port, collects receiver source network based on information carried message, stores local link state database; collected are synchronized to other SPB devices network, receivers sources by BEP stored if exists of device, searches database determine whether corresponding or not; table item between target accessed is established forwarded item. According waste broadband resources can be avoided.
