Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to Chinese Patent Application No. 202311532343.8, filed with the China National Intellectual Property Administration on November 15, 2023 and entitled "ROUTING DEVICE CONFIGURATION METHOD AND ROUTING DEVICE", which is incorporated herein by reference in its entirety. TECHNICAL FIELD Embodiments of this application relate to the field of communication technologies, and in particular, to a routing device configuration method and a routing device. BACKGROUND A routing device, for example, customer premise equipment (customer premise equipment, CPE), may be used to establish a home or office network connection. The routing device supports two networking modes: a routing mode and a bridge mode. In the routing mode, the routing device allocates a new IP address to a device connected to the routing device, and data exchange between the device and an upper-layer server is forwarded by the routing device. In the bridge mode, the routing device directly forwards, to a device connected to the routing device, a public IP address allocated to the routing device by a server connected to the routing device, and the device directly exchanges data with the server. In the bridge mode, the routing device serves only as a transit device without processing data. Only one device connected to the routing device is able to connect to the Internet at a time. This cannot meet a requirement for access of a plurality of devices when the routing device is in the bridge mode. SUMMARY Embodiments of this application provide a routing device configuration method and a routing device, to connect to a plurality of devices in a bridge mode. According to a first aspect, a routing device configuration method is provided. The method may be performed by a routing device, or may be performed by a module, a unit, or a chip in a routing device. The method includes: receiving first configuration information, where the first configuration information indicates to configure N downlink interfaces of the routing device to be in a bridge mode, and N is a positive integer greater than 1; creating N virtual bridge interfaces based on the first configuration information; configuring the N downlink interfaces and N uplink interfaces of the routing device on the N virtual bridge interfaces, where one uplink interface and one downlink interface are configured on each of the N virtual bridge interfaces, uplink interfaces configured on different virtual bridge interfaces are different, and downlink interfaces configured on different virtual bridge interfaces are different; and configuring wide area network IP addresses of the N uplink interfaces on the N downlink interfaces, where wide area network IP addresses configured on different downlink interfaces are different. Optionally, the first configuration information indicates an access point name (APN) corresponding to each of the N downlink interfaces, APNs corresponding to different downlink interfaces are different, and each APN corresponds to one uplink interface. A first downlink interface of the N downlink interfaces is used as an example. Configuring the N uplink interfaces of the routing device on the N virtual bridge interfaces includes: configuring, on a first virtual bridge interface based on an APN corresponding to the first downlink interface, a first uplink interface corresponding to the APN. In the foregoing implementation, a plurality of virtual bridge interfaces (bridge) are set on the routing device, one uplink interface is set on each virtual bridge interface, and one downlink interface (for example, a LAN interface or a Wi-Fi interface) is mounted to the virtual bridge interface, so that the uplink interface is bridged to the downlink interface, and the routing device can be connected to a plurality of devices of CPE in the bridge mode. In a possible implementation, the N downlink interfaces include N local area network LAN interfaces, or the N downlink interfaces include N Wi-Fi interfaces, or the N downlink interfaces include at least one LAN interface and at least one W-Fi interface. In a possible implementation, the routing device includes CPE. In a possible implementation, the method further includes: separately configuring routing rules corresponding to the N virtual bridge interfaces, where the N virtual bridge interfaces include a first virtual bridge interface, and data transmission between an uplink interface and a downlink interface that are configured on the first virtual bridge interface complies with a routing rule corresponding to the first virtual bridge interface. In a possible implementation, the first configuration information further indicates to configure M downlink interfaces of the routing device to be in a routing mode, where the M downlink interfaces are different from the N downlink interfaces, and M is a positive integer. A second virtual bridge interface is created based on the first configura
