Abstract

The embodiment of the invention provides a method for accessing a VXLAN (Virtual eXtensible Local Access Network) from a VLAN (Virtual Local Access Network), a device and a system. The method comprises the following steps: configuring a VXLAN sub-network on VXLAN gateway equipment, wherein network segment information of the VXLAN sub-network is the same as that of a VLAN sub-network correspondingto VLAN gateway equipment; configuring a gateway Internet protocol IP address and a gateway media access control MAC address of the VXLAN sub-network respectively as an IP address and an MAC address of the VLAN gateway equipment; and creating a first logical link between the VXLAN gateway equipment and first VTEP (VXLAN Tunneling End Point) equipment, and configuring the first logical link as a logical link outside the VXLAN, so as to enable the VXLAN sub-network to communicate with the VLAN sub-network. The embodiment of the invention can enable the VLAN to access the VXLAN, provide conditions for VM (Virtual Machine) migration, reduce the implementation cost, and reduce the error probability at the same time.

Description

technical field [0001] The present application relates to the technical field of network communication, in particular to a method, device and system for accessing a VXLAN network from a VLAN network. Background technique [0002] A virtual extensible local area network (Virtual eXtensible Local Access Network, VXLAN) is an extension of a virtual local area network (Virtual Local Access Network, VLAN), and is a network that builds the second layer on the third layer. VXLAN expands the number of Layer 2 network segments by encapsulating Layer 2 data into User Datagram Protocol (UDP). [0003] With the emergence of cloud data centers using VXLAN gateways, service migration may be required between traditional data centers using VLAN gateways and cloud data centers using VXLAN gateways. In traditional data centers using VLAN gateways, server virtualization technology is generally used to carry out services. Based on this, service migration between a traditional data center usin...
