Layer-3 Switch inter-Vlan routing experiment record

Note: switchport mode trunk can run directly on the 2950 switch, which enables 802.1q directly. To enable the relay function on vswitches such as 3550 and 4500, you must first select the encapsulation method, that is, run switchport trunk encapsulation dot1q.
