Layer-3 Switch for Cisco switches
Although single-arm routing solves the communication problem between different VLANs, it also has its fatal defects:
-The single arm itself is the Backbone link of the network, which is easy to form a network bottleneck.
-The sub-interface relies on physical interfaces, and the application is not flexible
-You need to view the route table for each vlan forwarding, wasting
"hard" operations on network devices. The security factor is high, but the obtained information is not accurate. For example, if the IP address of a server has been changed, we can think that the server is not connected to the network because the original IP address cannot be found on the switch. The system administrator first checks the IP address information on the server, and then finds out which port of the s
