Embodiment approach

[0038] In this implementation manner, the first device is further configured to, after sending a member link failure notification to the second device, send a notification to the second device when it detects that its own link aggregation group has recovered. Member link failure recovery notification. Correspondingly, the second device is further configured to restore port isolation between its own link aggregation group and the Peer-Link port when receiving the member link failure recovery notification. This operation prevents the service traffic received from the Peer-Link port from being forwarded through Link-Agg2, causing DHD2 to receive two copies of the same message.

[0039] A message forwarding method provided by the embodiment of this application, such as image 3 As shown, the following will combine image 3 Describe the steps involved.

[0040] Step S101: the first device determines that its own link aggregation group is faulty.

[0041] combine figure 1 To de...

Abstract

The present application relates to a message forwarding method and device, a dual-active system and communication equipment, and belongs to the technical field of communication. The method includes: the first device determines that its own link aggregation group is faulty; the first device adds the Peer-Link port as a member port to the link aggregation group; When sending packets, the service packets are forwarded from the Peer-Link port based on the address entry before the failure. When the link aggregation group of the first device fails, the Peer-Link port is added to the link aggregation group as a member port, so that the address entry originally added to the link aggregation group of the first device is not changed. In this way, all the service traffic that needs to be forwarded through the link aggregation group is forwarded to the second device through the Peer-Link port for processing, so that the performance of service traffic fault recovery is optimized.

Description

technical field [0001] The present application belongs to the technical field of communication, and in particular relates to a message forwarding method and device, a dual-active system and communication equipment. Background technique [0002] MLAG (Multi-Chassis Link Aggregation Group, cross-device link aggregation group) is a mechanism to realize cross-device link aggregation, which connects a DHD (Double-homed Device, dual-homed device) device with two other configuration devices ( MLAG node) to perform cross-device link aggregation to form a dual-active system. The application scenarios are as follows figure 1 shown. Link-Agg1 on node 1 (represents the link aggregation group numbered 1) and Link-Agg2 on node 2 (represents the link aggregation group numbered 2) and Link-Agg20 of DHD2 (represents the numbered 20 Link Aggregation Group) constitutes an inter-device Link Aggregation Group. Therefore, Link-Agg1 and Link-Agg2 belong to the same MLAG port, which is assumed to...
