Abstract

The invention provides a forwarding table synchronization method, network equipment and system. The data plane of the first network device receives the first message sent by the multi-homing access device; sends the first message to the control plane of the first network device; adds MC-LAG to the first message identify, obtain the second message, and send the second message to the data plane of the second network device through the data forwarding channel; the control plane of the first network device according to the first network device on the first network device The inbound port of a message and the first message generate a forwarding entry, update the first forwarding table in the control plane of the first network device according to the forwarding entry, and send the forwarding entry to all The data plane of the first network device; the data plane of the first network device updates the second forwarding table in the data plane of the first network device according to the forwarding entry. Through the present invention, the synchronization of the forwarding tables of each network equipment in the virtual cluster can be realized.

Description

technical field [0001] The invention relates to the communication field, in particular to a forwarding table synchronization method, network equipment and system. Background technique [0002] Link Aggregation Group (English: Link Aggregation Group, referred to as: LAG) is an inverse multiplexing (English: inverse multiplexing) method based on multiple Ethernet links, which bundles multiple links connected to the same device together , which can increase link bandwidth and provide redundant backup to improve link reliability. Multiple links in a link aggregation group can be regarded as a logical link. In Ethernet, there is a one-to-one correspondence between links and ports. Therefore, link aggregation is also called port aggregation. All ports in a link aggregation group share the same MAC address. [0003] Multi-Chassis Link Aggregation Group (English: Multi-Chassis Link Aggregation Group, referred to as: MC-LAG) is a device-level redundancy added to the link-level red...
