Abstract

The present application provides a proxy response method and device for a MAC address. In this method, at first receive the request message that the exchange that connects sends; Then according to the destination IP address of described request message query adjacency ADJ suppression table; , performing a proxy response to the request message; under the second configuration condition, if an entry corresponding to the destination IP address is found, compare the interface information in the entry with the information carried in the request message interface information, and the virtual local area network identifier VID information in the entry and the VID information carried by the request message are all the same; if they are all the same, the request message is discarded; otherwise, the request message is processed Agent answers. In the above method, the conflict between the request message answered by the agent and the message answered by the destination host is used to solve the problem that the forwarding path of the two-layer traffic is uncontrolled.

Description

technical field [0001] The present application relates to the technical field of computer communication, in particular to a proxy response method and device for MAC addresses. Background technique [0002] VXLAN (Virtual eXtensible LAN, Virtual Extensible Local Area Network), is an overlay network technology, a virtual Ethernet built on a physical IP (Internet Protocol, Internet Protocol) (underlay) network, using MAC (Media Access Control, Media Access Control) in UDP (User Datagram Protocol, User Datagram Protocol) method for encapsulation, a total of 50 bytes of encapsulation header, with a 24-bit VXLAN identifier VNI (VXLANNetwork Identifier, Virtual Extended Local Network Identifier), breaking Currently widely used VLAN (Virtual Local Area Network, Virtual Local Area Network) can represent a limit of 4096 isolated networks, enabling users to create 16777216 mutually isolated virtual networks to meet the needs of multi-tenant environments and scale expansion. Tunnel enc...
