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.
