Through the previous experiment we learned that by configuring VLANs, the terminals under different VLANs could not communicate with each other, but if you wanted to communicate between different VLANs, you would need to configure inter-VLAN routingLayer three switches have the capability of the network layer and can be forwarded via the routing functionNetwork environment1 set the IP address and gateway of the terminal (192.168.1.1 and 192.168.2.1, respectively).2 VLAN is configured under Layer

that the admin domain is able to overwrite all branch switches. The Cisco switch is capable of supporting any media as a trunk, and it can use its own ISL tags for relaying. ISL (Inter-Switch link) is a protocol between switches, between switches and routers, and between switches and servers to transfer multiple VLAN information and VLAN data streams, configured with ISL encapsulation via ports directly connected to the switch, The VLAN allocation a

"Introduction" Within a switched network, it is possible to segment and organize flexibly through VLANs. VLANs can group devices in a LAN. A group of devices in a VLAN communicates as if it were connected to the same line. VLANs are based on logical connections, not physical connections. Types of VLANsThere are many different types of VLANs used in modern networks. Some VLAN types are defined by traffic category. Some other VLAN types are defined by specific features.Data VLAN: used to deliver u

The loop has a great impact on the network. Spanning Tree protocol is a good solution to this problem.The idea of spanning a tree protocol topology is that, regardless of the physical connection between switches, the switch can automatically discover a network with no loop topology, and the network of the logica
