Inter-VLAN routing design
Choose between router-on-a-stick and a Layer 3 switch as VLANs scale up.
Host A (VLAN 10)
Switch
Router-on-a-stick
Host B (VLAN 20)
This is router-on-a-stick: VLAN 10 and VLAN 20 both reach the router over the same switch-to-router link. Configure that link, then test VLAN 10 reaching VLAN 20.
