Embodiment Construction
[0027] The present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0028] An embodiment of the present invention provides a method for optimizing spanning tree topology calculation in the case of stacking devices in a spanning tree network environment. When the user needs to consider the impact of the stacking topology on the spanning tree topology, the optimization function of the present invention is turned on, and the path overhead value in the spanning tree protocol BPDU (bridge protocol data unit, bridge protocol data unit) message is increased to reflect the stacking device At the same time, the hop count TLV field is added to the BPDU message to notify the downstream that the BPDU message passes through the internal hop count of the stacking device. On the basis of not changing the existing spanning tree protocol algorithm, the non-root bridge device can choose The port where the optimal for...
