How to use a vro to connect different VLANs of a single-layer switch

How to use a vro to connect different VLANs of a single-layer switch

Some simple configurations of the experiment

First configure PC

PC1 IP: 192.168.1.1 subnet mask: 255.255.255.0 Gateway: 192.168.1.254

PC2 IP: 192.168.1.2 subnet mask: 255.255.255.0 Gateway: 192.168.1.254

PC3 IP: 192.168.2.1 subnet mask: 255.255.255.0 Gateway: 192.168.2.254

PC4 IP: 192.168.2.2 subnet mask: 255.255.255.0 Gateway: 192.168.2.254

PC1 and switch SW1 ports f0/1 PC2 and switch SW1 ports f0/2 PC3 and switch SW2 ports f0/1 PC4 and switch ports f0/2

Switch SW1 and switch SW2 ports f0/3

Vro port g0/0 and vswitch SW1 port f0/4 vrog0 port g0/1 and vswitch port f0/4

Note (the red font is the key command)
