Interface configuration updating method and device for VRF resource allocation, and electronic equipment

The invention provides an interface configuration updating method and device for VRF resource allocation, and electronic equipment. The interface configuration updating method comprises the steps of: updating a VRF corresponding to a target interface in response to an interface updating instruction, and generating configuration information and an IP address of the target interface; writing an interface name, a VRF identifier and a state identifier of the target interface into a preset data table according to the configuration information, and sending a configuration updating instruction including the configuration information to a user state program; after a user mode program completes configuration updating of the target interface, setting the state identifier of the target interface in the preset data table as a preset value; and reading the preset data table, and sending an IP address setting instruction to the user mode program when the state identifier of the target interface is the preset value, wherein
