The switch has been configured with two vlans.and route-on-a-stick is being configured on the router for inter-vlan routing. A trunk is configured to connect the switch to the router. What is the minimum number of router subinterfaces that are required for all the vlans to communicate?
A.
one
B.
three

It can be done with one subinterface only.. Just configure the physical interface as though it was for untagged traffic for the native vlan (for example, vlan 1), and only one subinterface for the second vlan’s tagged traffic. So the correct answer should be A.
