Embodiment Construction
[0036] Different from the traditional daisy chain or ring connection methods, the stacking architecture method described in the present invention is to realize random unrestricted links, and the network routing and switching devices do not need to distinguish between routers or switches, and can be stacked after stacking Establish a complete topology system, and are not bound by the way of linking each other.
[0037] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0038] figure 2 It is a link diagram of a stacking system of routing and switching devices according to an embodiment of the present invention. Today, as network device interfaces tend to expand infinitely, multiple stack interfaces are required to ensure the return path. By adopting the stacking establishment method of the present invention, a direct connection can be established between any two devices, thereby ensuring that any t...

The invention relates to a method to stack the routing exchange equipment, which is applied in the stacking system containing at least two stacking equipments and can realize the mixed stacking of the router and the exchanger. The stacking equipment can send and receive the neighbor detection packets by the stacking interfaces after the starting, the packets at least contain the MAC addresses of the stacking equipments; the MAC addresses of the neighbor equipment can be obtained after the receiving of the neighbor detection packets which are sent by the neighbor equipments; the stacking topological information packets can be generated according to the information of the stacking interfaces and the information of MAC addresses of the neighbor equipments, the packets can be flooded to otherstacking interfaces except the receiving stacking interface of the packets; all the stacking equipments can select the main equipment according to the generated and received stacking topological information packets of their own, so as to obtain the topological mapping table of the whole topological system, and the topological mapping table is the mapping table of the information of the stacking interfaces and the information of the MAC addresses of the stacking equipments.
Description
technical field [0001] The invention relates to the field of data communication, in particular to a method for stacking routing and switching equipment. Background technique [0002] Routing and switching equipment is the most important and core component of the Internet, responsible for Internet routing propagation and traffic forwarding. Routing and switching equipment includes routers and switches. Managers decide the deployment of routers and switches according to network planning. As the scale of the network becomes larger and the number of routing and switching devices increases, the complexity of its management increases exponentially. On the one hand, in order to realize the management of each device, complex networking is often required, down to the individual configuration of each relevant interface of each device. When the network is complex, there are often many configurations. Once the network planning changes, The modified configuration workload and impact are...
