Experiment on single-arm routing using a layer-3 Switch

Experiment on single-arm routing using a layer-3 Switch

In the real environment, sometimes the gateway is not necessarily enabled on the router, sometimes the single-arm routing function is not necessarily connected to the interface on the router, you can use a layer-3 switch, because the vswitch itself has a variety of interfaces for flexible use, it is very common in practical work. Readers can compare the previous article "using single-arm routing Experiment Sub-interfaces" to find out the secrets.

The specific operations are as follows:

Background description: Two VLANs (vlan 501/406) are required on the switch1-2950T-24. vlan 501 uses the first 10 ports, vlan406 uses port 0/11-0/20, and vlan 501 uses the 10.63..0 .0/24 network segment; vlan 406 uses the 10.63.206.0/25 network segment, the gateway uses the last available address, and the management address vlan 1 uses 10.63.207.128/25.
