Example Embodiment

[0034] Different from the traditional daisy chain or ring connection method, the stacking architecture method of the present invention is to realize random and unrestricted links, network routing and switching equipment, no need to distinguish between routers or switches, all can be stacked after stacking. Establish a complete topological system, and each other is not restricted by the way of linking.

[0035] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0036] Fig. 2 is a link diagram of a stacking system of routing and switching equipment according to an embodiment of the present invention. Today, network device interfaces tend to expand infinitely, and multiple stacking interfaces are needed to realize the guarantee of return. By adopting the stacking establishment method of the present invention, a direct connection can be established between any two devices, thereby ensuring that there are separate links be...

Abstract

A method for stacking routing and switching devices is applied to a stacking system including at least two stacking devices, and can realize mixed stacking of routers and switches. After the stacking device is started, it sends and receives a neighbor detection message through the stacking interface, and the message contains at least the MAC address of the stacking device; and obtains the MAC address of the neighbor device after receiving the neighbor detection message sent by the neighbor device ; Then generate a stack topology information packet according to the stack interface information and the MAC address information of the neighbor device, and send it to the stack interface of the neighbor device; Other stacking interfaces other than the stacking interface flood the packet; all stacking devices select the master device according to the stacking topology information packets generated and received by themselves, and obtain the topology mapping table of the entire topology system. The topology mapping table is the stacking interface information Mapping table with stack device MAC address information.

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...
