Abstract
A method resolves connectivity of services inside a network virtualization system when a virtual cluster system supports unicast IP, L2VPN, and L3VPN services, so that the software network virtualization system can support various types of services efficiently and with high quality. The method includes: creating, on a control device, a virtualized remote logical interface for an external interface of a remote access node; identifying, by the control device 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 a core aggregation node; and sending, by the control device, the virtual link forwarding entry to the remote access node and the core aggregation node, so as to set up a virtual link between the core aggregation node and the remote access node.
