1. A transmission pipe configuration method, comprising:
receiving, by a controller, from a first border transport device, a device address of a first network domain;
receiving, by the controller, a device address of a second network domain from a second border transport device, wherein the controller is configured to centrally control a transport network that comprises the first border transport device and the second border transport device, wherein the transport network is configured to connect the first network domain and the second network domain, wherein the first network domain comprises a first border device, wherein the second network domain comprises a second border device, wherein the first border transport device is connected to the first border device, and wherein the second border transport device is connected to the second border device;
generating, by the controller, an identifier of a transmission pipe based on the device address of the first network domain and the device address of the second network domain, wherein the transmission pipe connects the first border transport device and the second border transport device; and
sending, by the controller, to the first border transport device, the identifier of the transmission pipe and the device address that is of the second network domain and that corresponds to the transmission pipe, wherein the identifier of the transmission pipe and the device address that is of the second network domain and that corresponds to the transmission pipe are used to generate a forwarding table of the first border transport device, and wherein the forwarding table of the first border transport device indicates a forwarding relationship in which service data is forwarded from the device address of the first network domain to the device address of the second network domain using the transmission pipe.
