Problems solved by technology

When a BUM (Broadcast / Unknown unicast / Unknown Multicast, broadcast / unknown unicast / unknown multicast) message is received from the access device C, assuming that the BUM is determined to be uplinked to the DR device A through a hash (hash) operation, because It is a BUM message, which will continue to be forwarded by DR device A to DR device B via IPL, which will occupy the IPL bandwidth and waste IPL bandwidth resources

Embodiment Construction

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0036] In order to save IPL bandwidth resources, embodiments of the present invention provide a message forwarding method, device, access device, DR device, and machine-readable storage medium. In the following, the message forwarding method provided by the embodiment of the present invention is firstly introduced.

[0037] The message forwarding method provided by the embodiment of the present invention is applied to a DR system, and the DR system includes an...

Abstract

Embodiments of the present invention provide a message forwarding method and device. After receiving an uplink message to be forwarded, an access device judges whether the message to be forwarded is a known unicast message. If the message to be forwarded is not If the unicast message is known, the message to be forwarded is forwarded to the sub-DR groups that belong to the same aggregation sub-group as the uplink port groups through the pre-divided uplink port groups. After the DR device in each sub-DR group receives the message to be forwarded, if it recognizes that the message to be forwarded carries the aggregation subgroup identifier, it forwards it to other neighbor devices except the neighbor DR device of the sub-DR group The message to be forwarded. Through this solution, bandwidth resources of the IPL can be saved.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a message forwarding method and device. Background technique [0002] MLAG (Multi-chassis Link Aggregation Groups, cross-device aggregation) 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. DRNI (Distributed Resilient Network Interconnect) is a cross-device link aggregation technology. In a typical DRNI network, two DR (Distributed Relay, distributed aggregation) devices form a DR system through Ethernet link aggregation. . [0003] DRNI defines the following interface roles for each DR device: DR interface and IPP (Intra-Portal Port, internal control link port). The DR interface is a Layer 2 aggregation interface that connects the DR device to external devices. The local DR device and the neighbor DR device are connected to ...
