摘要
Priority of a route, which carries a virtual extensible local area network (VXLAN) tunneling end point (VTEP) Internet protocol (IP) address of a port of a VXLAN tunnel corresponding to a first VXLAN IP GW to be migrated, is lowered. The route is then released to a VTEP at peer end of the VXLAN tunnel. Priority of a static route destined for a virtual machine (VM) is also lowered. The static route is then released to a network device in a non-virtual network. At least two VXLAN IP GWs possess a same VTEP IP address of a port of a VXLAN tunnel. Before priority of route corresponding to first VXLAN IP GW is lowered, priority of route carrying the same VTEP IP address released by each of at least two VXLAN IP GWs is same. Priority of static route from each of at least two VXLAN IP GWs to the VM is same. When controller monitors no data flow between VM and network device in the non-virtual network passes the first VXLAN IP GW, migration actions may be executed.
