Abstract

A method for forwarding a message is provided in an embodiment of that present disclosure, switches and computer-readable storage media, relating to the technical field of communication.When a distributed aggregation port of the first network device fails, transmitting the message to be forwarded to the second network device through the IPL corresponding to the IPP added to the distributed aggregation interface, the MAC table entry and the ARP table entry corresponding to the IP address of the target network device learned by the DR device A and the DR device B are reserved, there is no need to re-receive the message and re-learn the forwarding table item corresponding to the Internet protocol address of the target network equipment, so that the switching speed of the message forwarding ofthe DR system is greatly improved and the packet loss is reduced.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular, to a message forwarding method, a switch, and a computer-readable storage medium. Background technique [0002] Cross-device link aggregation technology (Multi-chassis link aggregation groups, referred to as: MLAG) realizes cross-device link aggregation by virtualizing two physical devices into one device at the aggregation level, thereby providing device-level redundancy protection and traffic load Sharing, and Distributed Resilient Network Interconnect (DRNI for short) is a concrete implementation of the MLAG idea. [0003] In the prior art, in a network using distributed link aggregation technology for networking, if there is inter-device port aggregation between devices, a distributed relay (Distributed Relay, DR for short) is formed between these devices. ) system, these DR devices in the DR system are neighbors to each other, and the devices that are neig...
