<p>The present invention relates to the field of network communication, and in particular, to a method for sending Ethernet frames in an Ethernet Tree service and a provider edge device. The method includes: receiving, by a virtual local area network VLAN bridge, Ethernet frames sent by a root node or a leaf node; importing, by the VLAN bridge, the Ethernet fames into a root VLAN or a leaf VLAN according to the type of the node sending the Ethernet frames, and sending the Ethernet frames to a same virtual switch instance VSI, wherein the VSI is connected to the VLAN bridge by using at least one root VLAN and at least one leaf VLAN; and sending, by the VSI, the Ethernet frames to a corresponding remote provider edge PE device by a pseudowire. Using the technical solution provided in the embodiments of the present invention, a VLAN is associated with the type of the node sending the Ethernet frames, thereby achieving effective isolation between the E-Tree leaf nodes and ensuring the original scalability of VPLS.</p> |
