Claim:
1. A method for data transmission of network virtualization, comprising: creating, on a core aggregation node, a virtualized remote logical interface for an external interface of a remote access node, wherein the external interface of the remote access node is an interface that is configured to connect to another network device; identifying, by the core aggregation node according to a service configured on the virtualized remote logical interface, a service type of the service, and generating virtual link forwarding entries of the remote access node and the core aggregation node, wherein the virtual link forwarding entry comprises a virtual link forwarding entry of the core aggregation node and a virtual link forwarding entry of the remote access node, and wherein an interface of an attachment circuit in the virtual link forwarding entry of the core aggregation node is the virtualized remote logical interface; storing, by the core aggregation node, the virtual link forwarding entry of the core aggregation node; and sending, by the core aggregation node, the virtual link forwarding entry of the remote access node to the remote access node, so as to set up a virtual link between the core aggregation node and the remote access node.
