H3C layer-3 Switch configuration: Analyze VLAN code instances

H3C layer-3 Switch configuration: analyzes VLAN code instances. Currently, there are a lot of people using layer-3 switches, and maintenance of switches has become a problem that cannot be ignored. Only the three-tier switch is configured, which not only saves your time and effort on accessing the Internet, but also brings more highlights to your network life.

Note: There are three VLANs, 192.168.10.0; 192.168.20.0; 192.168.30.0, And the subnet mask is 255.255.255.0. ethernet 1/0/1, Ethernet 1/0/2, and Ethernet 1/0/3 are allocated to three VLANs respectively. Therefore, the three VLANs can be interconnected through layer-3 switching routing.

Supplement: "After a VLAN is configured for a layer-3 Switch, no direct communication is allowed between VLANs. If you need to communicate, you can use the layer-3 interface configured for the layer-3 Switch to enable communication between two VLANs through layer-3 forwarding. "For the specification, I cannot find the layer-3 Switch configuration. I hope you can help us solve this problem. It is best to have complete code and explanations, or use the H3C3 layer switch code. You can find the layer-3 Switch configuration code on the Internet. If you can help me solve the problem, continue to deliver points.

By default, the routing function is enabled for switches. layer-3 switches cannot directly communicate with each other through VLAN interface addresses for layer-3 forwarding. The computer gateway address in each VLAN can be set as the corresponding VLAN interface address. Delete the layer-3 Switch configuration file and try again.
