Abstract
A method for establishing a Virtual Local Area Network (VLAN) connection is provided, which includes: receiving a first signaling message, in which the first signaling message includes an unused VLAN ID and explicit routing information; registering the VLAN ID by using the at least one unused VLAN ID; and sending the first signaling message according to the explicit routing information. Several node apparatuses and several systems are also provided in the present invention. Therefore, automatic VLAN configuration is performed in an environment without a spanning tree protocol, and traffic engineering is supported simultaneously.
