Abstract

The invention provides a layer 2 forwarding table item aggregation method and a layer 2 forwarding table item aggregation device, applied to switch equipment. The method comprises the following steps of: acquiring multiple layer 2 forwarding table items under the same port, wherein the layer 2 forwarding table items are used for recording a corresponding relationship of a media access control MAC address of a virtual machine VM and the port; and merging the multiple layer 2 forwarding table items under the same port according to a predefined MAC address allocation rule of the VM. With the method and the device provided by the invention, the number of the layer 2 forwarding table items in the switch equipment can be reduced, the requirement on storage space of the switch equipment is lowered, and the system resource of the switch equipment is saved.

Description

technical field [0001] The present application relates to the technical field of network communication, and in particular to a layer-2 forwarding entry aggregation method and device. Background technique [0002] A data center usually adopts a server virtualization technology to virtualize a physical server into multiple VMs (Virtual Machines, virtual machines). In a large Layer 2 network using VXLAN (Virtual eXtensible LAN, scalable virtual local area network) technology, physical servers are usually required to support VXLAN technology, so that Layer 2 packets sent by VMs are encapsulated at Layer 3, and then the switching device performs Layer 3 encapsulation. layer forwarding. Therefore, the increase in the number of VMs will not affect the processing capability of the switching device. [0003] However, when there is a traditional physical server in the VXLAN network, because the traditional physical server does not support VXLAN technology, it cannot perform Layer 3 ...
