Abstract

The invention provides a message forwarding method and a message forwarding device. The method comprises steps: when a broadcasting message needs to be transmitted through a target stacking port, first indication information is determined according to a stacking topology, and the broadcasting message carrying the first indication information is transmitted through the target stacking port, wherein the first indication information is used for indicating a member device to which the broadcasting message is forbidden to be forwarded; when the broadcasting message is received, according to the first indication information carried in the broadcasting message, whether to allow to forward the broadcasting message to a neighbor member device is judged; if yes, the first indication information carried in the broadcasting message is updated according to the stacking topology, and the updated broadcasting message is forwarded to the neighbor member device; or otherwise, forwarding of the broadcasting message to the neighbor member device is denied. When the embodiment of the invention is applied, the broadcasting message can be prevented from generating a loop in a stacking system.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a message forwarding method and device. Background technique [0002] The basic idea of ​​IRF (Intelligent Resilient Framework, Intelligent Resilient Framework) virtualization technology is to connect multiple devices together, configure them, and virtualize them into one device for management. This process may also be referred to simply as stacking. [0003] In a stack system, unicast traffic and broadcast traffic are forwarded. The destination port is specified for unicast traffic, and the traffic is only sent to the destination outbound port without forming a loop. The broadcast traffic is broadcast to other boxes, and after other boxes receive it, they will be forwarded to the sender through the stack link, thus forming a loop. The loop will occupy the bandwidth of the stacking link, affect the forwarding of protocol packets, and may also impact the CPU (Cent...
