Abstract

The invention provides an MAC address proxy response method and device. The method comprises the following steps: firstly, receiving a request message sent by a connected switch; querying an adjacentADJ suppression table according to the destination IP address of the request message; under a first configuration condition, if a table entry corresponding to the destination IP address is queried, performing proxy response on the request message; under a second configuration condition, if a table entry corresponding to the destination IP address is queried, comparing whether interface informationin the table entry is the same as interface information carried by the request message, and whether VID (Virtual Local Area Network Identifier) information in the table entry is the same as VID information carried by the request message; if YES, discarding the request message; and otherwise, performing proxy response on the request message. Via the method, the problem that a two-layer flow forwarding path is not controlled due to conflict between the request message responded by a proxy and the message responded by a target host is solved.

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.
