Now you need to configure the router to send traffic between VLANs. To do this, you must configure a subinterface on the router for each VLAN. Recall this means you$$re dividing the one physical interface into two logical interfaces. But first, you must remove the IP address configuration on the physical interface so you can use this IP address space for the subinterfaces. Complete the following steps:

Now, because you$$ve adjusted the subnetting for these devices, go back to each of the four PCs and update their IP configuration information to reflect the correct subnet and the correct default gateway, as needed. What information did you change? Also update your notes for all involved devices as needed.
