the device also comprises a second control module, wherein the second control module is used for controlling the virtual router to operate the radvd component, so that the virtual router sends a route notice to a corresponding subnet according to the network address of the internal interface, and the route notice identifies that the gateway address of the subnet is the network address of the internal interface of the virtual router.
5. A web server, comprising: at least one processor and memory;
the memory stores computer-executable instructions;
the at least one processor executing computer-executable instructions stored in the memory causes the at least one processor to perform the cloud platform network configuration method of any of claims 1 to 3.
6. A computer storage medium having stored therein computer executable instructions which, when executed by a processor, implement the cloud platform network configuration method of any of claims 1 to 3.
7. A cloud platform system, comprising: at least one control server, at least one network server, and at least one computing server;
the network server is used for executing the cloud platform network configuration method according to any one of claims 1 to 3;
