The techniques describe a network device comprising one or more processors configured to: receive configuration data configuring a plurality of virtual network nodes, wherein the configuration data configures a virtual client node including a corresponding line card having a port connected to a first customer network device, and configures a virtual core node including a corresponding line card having a port connected to a core network; provision a layer-2 (L2) circuit that includes, as an access interface, an interface logically connecting the virtual client node and virtual core node, wherein the L2 circuit provides connectivity between the virtual client node and a remote virtual client node; and forward, via the L2 circuit, packets between the virtual client node and the remote virtual client node to realize a logical network between the first customer network device and a second customer network device connected to the remote virtual PE node.
