Background
In some security-demanding scenarios, to achieve network isolation for different scenarios, multiple different VRFs are created on the network device, which by default are all network-isolated. Each VRF has an independent routing table and a physical interface, and generally, in order to reduce resource consumption such as memory, the application programs of the network devices do not implement network isolation based on different VRFs.
When the operating system of the network device is Linux/Unix, the operating system includes a user space and a kernel, a technician can start an application program through a management program, and the application program of the current network device needs to establish Socket for communication with the application programs of other network devices. Because different VRFs in the network device implement network isolation, that is, the network device may have the same routing and Internet Protocol (IP) addresses, the Socket of the application needs to specify the belonging VRF to implement communication between the application and applications of other network devices. Generally, it is necessary to bind, in the kernel, the VRF to which the Socket of the application belongs.
At present, a method for binding Socket and VRF is to call a management process corresponding to a hypervisor to create a sub-process after detecting that the hypervisor in a user space receives a binding request carrying an application name and a VRF name; calling the subprocess to analyze the application program identifier corresponding to the application program name and starting the application program in the user space corresponding to the application program identifier; calling an application program to analyze the VRF ID corresponding to the VRF name and sending an adding request carrying the VRF ID and the PID of the sub-process to a kernel; calling a kernel to store the VRF ID and the PID in a kernel memory; calling an application program to send a Socket creating request carrying PID and Socket creating parameters to a kernel; calling the kernel to create a Socket corresponding to the application program based on the Socket creation parameter and the PID, and returning a description file corresponding to the Socket to the application program; and then, forwarding the message between the application program and the application program of other network equipment based on the VRF corresponding to the VRF ID of the Socket.
In the method, the application program can communicate with the application programs of other network devices under the specified VRF based on the Socket only by supporting the analysis function of the VRF related parameters, and the VRF corresponding to the Socket is set after the Socket of the application program is established.

When a technician needs to specify a VRF for an application, the application name and VRF name may be entered in the hypervisor, e.g., VRF1 may be specified for a ping, the application name is ping, and the VRF name is 1. After detecting that a binding request carrying an application program name and a VRF name is received by a management program in a user space, the network device can call a management process corresponding to the management program to create a sub-process.
