<p>The present invention relates to the field of network communications, and especially relates to a method for sending Ethernet frames in the Ethernet tree service and a Provider Edge (PE) device. The method includes: a Virtual Local Area Network (VLAN) bridge receives Ethernet frames sent from root nodes or leaf nodes; the VLAN bridge imports the Ethernet frames into a root VLAN or a leaf VLAN according to the types of nodes sending the Ethernet frames, and sends the Ethernet frames to a same Virtual Switch Instance (VSI), the VSI being connected with the VLAN bridge via at least one root VLAN and at least one leaf VLAN; and the VSI sends the Ethernet frames to the corresponding opposite PE device via Pseudo wires (PWs). By adopting the technical solutions provided by the embodiments of the present invention, the VLAN is associated with the types of the nodes sending the Ethernet frames, thus achieving effective isolation between leaf nodes of the Ethernet Tree (E-Tree) and guaranteeing the original extensibility of the Virtual Private LAN Service (VPLS).</p> |
