Embodiment Construction
[0050] The present invention will be described in detail below in conjunction with specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.
[0051] Such as figure 1 As shown, it is a schematic diagram of a basic MLAG networking structure according to an embodiment of the present invention, including a master device 10 and a backup device 20, and both the master device 10 and the backup device 20 may be switches. Here, the master device 10 and the backup device 20 can be selected according to certain rules, for example, by comparing the size of the MAC addresses of the two devices. In a special example, when the device selected as the master device fails, the backup device 20 Automatically switch to the master device 10. It should be noted ...

The invention discloses a method and an apparatus for realizing an STP (Spanning Tree Protocol) protocol family in an MLAG (Multi-Chassis Link Aggregation) environment. The method comprises the following steps: when a standby device port receives an original message, packaging standby device port information and the original message, and sending the same to a main device to obtain a main device port which is a mutual aggregate port of the standby device port, calculating to obtain a current port state of the main device port, sending the current port state information and the standby device port information to a standby device, after obtaining the current port state of the main device port, setting the state of the standby device port to be consistent with that of the main device port by the standby device to realize the effect that the port states of the main device port and the standby device port are synchronized. The method disclosed by the invention can be used for calculating according to the existing STP protocol family of the main device without carrying out special processing or changing the configuration information, the states of the aggregate ports can be synchronized just by synchronizing the calculation results, and the method disclosed by the invention is used for operating the STP protocol family in the MLAG environment in the minimum workload.
Description
technical field [0001] The invention relates to the field of network communication, in particular to a method and a device for realizing the STP protocol family under the MLAG environment. Background technique [0002] MLAG (Multi-ChassisLinkAggregation, cross-device link aggregation) is more stable and reliable than traditional box-type equipment, and its cost is lower than that of rack equipment. In the MLAG environment, each adjacent device uses a port for aggregation. From the perspective of other devices, the two aggregated ports are one port. [0003] STP (SpanningTreeProtocol, Spanning Tree Protocol) protocol family is the most basic two-layer protocol in network communication, including STP, MSTP (MultipleSpanningTreeProtocol, Multiple Spanning Tree Protocol) and RSTP (RapidSpanningTreeProtocol, Rapid Spanning Tree Protocol), the STP protocol family is the simplest The purpose of this is to prevent network loops from causing broadcast storms. Therefore, in an envir...
