(57) The present disclosure discloses a layer-2 dedicated line network system and a configuration method. The layer-2 dedicated line network system includes a system switch and a POP server, wherein the system switch is connected to the POP server on the same side, and the POP servers on different sides are connected by a layer-2 tunnel, wherein each port of the POP server is assigned a link cost value, where the ports connecting the different layer-2 tunnel have different link cost values. At the same time, only one layer-2 tunnel is in a forwarding state, if the layer-2 tunnel in the forwarding state is unavailable, a target layer-2 tunnel is selected from the remaining available layer-2 tunnels in accordance with the assigned link cost value and the target layer-2 tunnel is set in the forwarding state.
