Abstract: The present disclosure provides a method, apparatus and system for switching a virtual IP, relates to the field of artificial intelligence and particularly to cloud computing and cloud network technologies, and can be applied to intelligent cloud scenarios. A detailed implementation comprises: receiving a free ARP packet sent by a virtual machine to which a high-availability virtual IP is successfully switched; generating a first forwarding table of the high-availability virtual IP according to the free ARP packet; encapsulating the first forwarding table in a first UDP packet by VXLAN; and synchronizing the first UDP packet to another virtual router.
