A system comprises a router having stored thereon a respective incoming label table including at least one set of LSP information (e.g., a LSP designator, a label denoting normal flow routing functionality and a label denoting controlled flow routing functionality). The router is configured for receiving a plurality of different traffic flows each including a plurality of frames, for correlating a configuration of the flow routing label of each one of the frames received thereby to a respective one of the traffic flows using information contained in the incoming label table thereof, for flooding a frame of the traffic flows of the router to all local access ports on an active VPLS domain thereof when the frame requires normal flow routing functionality, and for dropping the frame without being flooded to all of the local access ports on the active VPLS domain when the frame requires controlled flow routing functionality.
