Abstract

This application discloses a BUM message suppression method, device and medium, which are applied in a network system. The method includes: the second leaf node judges whether the message is a BUM message; if so, adds a corresponding mark and forwards it to the third leaf node; the third leaf node discards the packet. By adding the corresponding mark in the BUM message, the network side node can no longer forward the message after receiving the message, which solves the problem of BUM message flooding in the Layer 2 broadcast domain, occupying network bandwidth, CPU resources of the device and MAC Address drift and other issues. And the networking mode based on MLAG has a larger application space. In MLAG-based VxLAN networking, after the CPU issues ACL rules, the switch chip controls packet forwarding, which can achieve wire-speed forwarding. BUM packets can be suppressed on a single network device without a network controller device.

Description

technical field [0001] The present application relates to the field of message forwarding, in particular to a BUM message suppression method, device and medium. Background technique [0002] At present, in the data center, in order to meet the development needs of cloud computing, a flat design method is usually used to construct a large layer-2 network by using the virtual extensible local area network (Virtual eXtersiable Local Area network, VxLAN) network technology, so that the data center can accommodate more virtual machine. In order to improve the stability and reliability of the data center network and avoid network communication problems caused by single point failures, the multichassis link aggregation technology (Multichassis LinkAggregation Group, MLAG) is usually used to form two leaf node (Leaf) devices into a span The link device aggregation group performs redundant backup and adopts the solution of multiple spine node (Spine) device access to improve the fau...
