Three-tier exchange
Layer switching technology is: Layer 3 forwarding switching technology + technology. After it solves the LAN segment divided segment in the subnet must rely on routers to manage the situation, to solve the network bottlenecks of traditional low-speed routers, complex caused.
Layer Configuration Experimental exchange:
operating area in the pull-in GNS3 two switches three PC.
After the previous two experiments where we do not set up the hardware switches were introduced. The next step is for the PC and the interface and IP address of the switch to plan,
This step we sw1 configuration of three interfaces, we first enter the global mode and turns off sw1 routing function, then we configure the three vlan, and then view the configuration result. After we interface f1 / 1 configured as vlan10, the interface f1 / 2 configured as vlan20, the interface f1 / 3 configured vlan30, the final configuration of view.
Here we would also like to sw1f1 / 0 interface configuration. We trunk configuration of the interface f1 / 0, after another look at the configuration.
In order to properly carry out the experiment, we also missed a configuration sw2. First we enter the global mode, configure the three vlan, then again on the interface f1 / 0 were trunk configuration. Then we need to configure the gateway IP corresponding to vlan10,20,30.
After another step in what we configure the IP address of the PC of the three.
All equipment configuration is complete, we can test the final splice. The results prove that we can be spliced such a configuration is successful.
