Explanation

R1 Subinterface Configuration (4.2.4) The router-on-a-stick method requires you to create a subinterface for each VLAN to be routed. A subinterface is created using the interface interface_id.subinterface_id global configuration mode command. The subinterface syntax is the physical interface followed by a period and a subinterface number. Although not required, it is customary to match the subinterface number with the VLAN number.
