摘要： This application provides a method, device, and system for processing a VXLAN packet. The method includes: obtaining, by a controller, a request message for requesting allocation of a VNI, obtaining the VNI and a VXLAN security policy corresponding to the VNI according to the request message, and delivering the VNI and the VXLAN security policy corresponding to the VNI to a network device. When encapsulating a VXLAN packet, a network device used as a transmit end applies the corresponding VXLAN security policy according to the VNI to encrypt the VXLAN packet. When decapsulating the VXLAN packet, a network device used as a receive end applies the corresponding VXLAN security policy according to the VNI to decrypt the encrypted VXLAN packet.
