In enterprise campus networks, a common design is to use a Huawei Layer 3 campus switch as S5730 series, while an upstream router provides Internet access. This article provides a complete configuration example, including CLI commands, to help engineers quickly deploy this. Layer 3 switches provide the routing function, which indicates a network-layer function in the OSI model. Layer 3 switches can work at Layer 2 and Layer 3 and be deployed at the access layer or aggregation layer as user gateways. This example uses router configurations of AR3600 V200R007C00SPCc00. The Layer 3. Multi-Brands Network Hardware meet your various demands. Cisco, HPE, Huawei, Dell, Junipe, EMC and others for you. As a leading global ICT solutions provider, Huawei's router and switch products play a key role in building advanced network infrastructures. So how are Huawei's routers and switches. Configuring inter VLAN routes on Huawei's layer-3 switches mainly includes creating VLANs, port division, layer-3 VLAN interface address configuration, static routing or rip protocol configuration. It is required that users access the Internet through the Layer 3 switch and router and that the Layer 3 switch functio.
