Embodiment Construction

[0037] An embodiment of the present invention provides a MAC address information notification scheme, which can be applied to an EVI network or a similar layer-2 interconnection network, such as an OTV (Overlay Transport Virtualization, Overlay Transport Virtualization) network. The following describes the embodiment of the present invention in detail by taking the application in the EVI network as an example.

[0038]In the embodiment of the present invention, in the EVI network, by increasing the EVI-ISIS parameter, the EVI site equipment (that is, the edge equipment of the site network, that is, the equipment in the EVI network) is allowed to compete, and the EVI main site equipment is elected, and the The primary site device takes over the synchronous processing of MAC address information, thereby reducing network traffic and reducing the transmission of invalid MAC address information between site devices.

[0039] In order to achieve the above purpose, the embodiment of ...

Abstract

The invention discloses a method and equipment for announcing media access control (MAC) address information. The method is applied to a virtualization network which consists of edge devices respectively in site networks of large two-layer interconnection. The method comprises the following steps of: competing for a primary device according to the priority by the edge devices respectively in the site networks in the same virtualization network case; sending a link-state packet (LSP) in which MAC address information required to be announced is packaged to the primary device when the edge devices respectively in the site networks need to announce the MAC address information if the device is a non-primary device; sending the LSP in which the MAC address information required to be announced is packaged to all neighbor devices of the device if the device is the primary device; and transmitting the received LSP to other neighbor devices except an LSP sender after the LSP in which the MAC address information is packaged is received by the edge devices respectively in the site networks if the device is the primary device. By adopting the method and equipment for announcing the MAC address information, network resources used during a process of announcing the MAC address information can be reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular to a MAC (Media Access Control, Media Access Control) address information notification method and device. Background technique [0002] With the increasingly frequent application of data centers in enterprises, issues such as data center interaction efficiency and security have increasingly become hot topics in the field of network data communications. The new generation of data centers is designed to support "cloud computing" services, and has the characteristics of high-speed network exchange capabilities, convenient network configuration methods, and support for decentralized establishment of remote databases. Among them, represented by the EVI (Ethernet Virtualization Interconnection, Ethernet Virtualization Interconnection) design scheme, a "Layer 2 forwarding based on a Layer 3 network" design is proposed, which makes the "physically distributed deployment, logically the same...
