The embodiment of the invention provides a network tab distribution method, equipment and a system and relates to the communication field. According to the invention, local PE can distinguish messages from different far-end PEs. The network lab distribution method comprises the following steps: the local PE generates VPN tab routes for each far-end PE, wherein VPN tabs in the VPN tab routes of different far-end PEs are different and the far-end PEs and the local PE at least belong to a same VPN; the local PE sends the VPN tab routes to the far-end PEs such that IP addresses of the far-end PEs match IP addresses of target equipment in the VPN tab routes, virtual routes of the far-end PEs forward access route target RT of VRF to match route target RT in the VPN tab routes and the far-end PEs carry the VPN tabs when sending messages related to successfully-matched VRF to the local PE. The network tab distribution method, the equipment and the system are used in network tab distribution.
