Abstract

The invention discloses a virtual machine migration method, an ARP proxy gateway and a VTEP. The method comprises: receiving virtual machine migration information sent by a cloud management platform, wherein the virtual machine migration information is sent after the cloud management platform migrates a virtual machine from a first physical host to a second physical host and at least comprises an IP address of the virtual machine; determining all VTEPs in a VNI where the virtual machine is located according to the IP address, a corresponding relationship between the IP address and the VNI pre-configured by an ARP proxy gateway and a corresponding relationship between the VNI and the VTEP; and sending MAC address generation information at least comprising the IP address to all VTEPs in the VNI where the virtual machine is located. The migration efficiency of the virtual machine can be improved.

Description

technical field [0001] The invention relates to the technical field of scalable virtual local area network, in particular to a virtual machine migration method, an ARP proxy gateway and a VTEP. Background technique [0002] In the VXLAN (Virtual eXtensible LAN, scalable virtual local area network) network, when VM1 (Virtual Machine, virtual machine) migrates from VTEP1 (VXLAN Tunnel End Point, VXLAN tunnel end point) to VTEP3, VTEP3 will migrate the extended community attribute corresponding to VM1 value (that is, the number value) plus 1, and then synchronize the EVPN routing information carrying the number value to VTEP1 and other VTEPs. After receiving the EVPN routing information, VTEP1 and other VTEPs will compare the number value in the EVPN routing information with the Number values ​​are compared, and when the number value in the EVPN routing information is greater than the maintained number value, the forwarding entry switching action for VM1 migration is performed....
