Application of Routing Communication between VLANs in A Layer 3 Switch

Abstract

With the rapid development of the economy and the continuous improvement of the level of science and technology, China's network communication has made great progress, and both have achieved a qualitative leap in communication quality and transmission rate, and these depend on the data processing speed. In the current era, people put forward higher requirements for data processing speed. As a LAN technology, VLAN is widely used in enterprises or campuses. Its main function is to isolate the broadcast domain. At present, the common method of implementing communication between VLANs is to use a single-arm router, but the one-arm router has the disadvantages of slow transmission speed and poor applicability. In recent years, the three-layer switch has played an increasingly important role in the routing and communication between VLANs. Its features of high scalability, strong applicability and good economy have been favored by people. This paper studies and analyzes the application of routing communication between VLANs in Layer 3 switches.
