ICMP Echos to 192.168.20.1, timeout is 2 seconds: .!!!! Success rate is 80 percent (4/5), round-trip min/avg/max = 24/48/84 MS From the above, we can see that through the deployment of layer-3 switching technology, the host between VLANs can communicate with each other. This experiment is complete. [PL1]Disable layer-3 routing to simulate hosts. [PL2]Define the default gateway. [PL3]Enable the layer-3 routing function. By default, the layer-3 Switch

Note on Switch configuration: (prevent forgetting it again)1. Check whether the vswitch version is consistent. If it is not a version or the version is relatively low, you need to upgrade it,Here, the 3cdaemon software is used as the server to facilitate file upload and download. Here, you need to note the upload and download paths. After setting, you must find the files to be uploaded and downloaded here.2
