my question was in figure 11.15 where it shows mutiple vlans hooked to switches and then those switches hooked to main switch and then hooked to router. since all the vlans are differnet subnets how does the router sort out the traffic...? I show only one input to router? i guess with ISL or 802.1Q? Also, the mention that you could have to it to where users from differnt vlans can access server without crossing layer 3 device...? I understand that server would plug into its own trunking port on the switch.. My basic question is can you have more than one trunking port on a switch. ie. the one that connects the switches together and one hooked to server?

one more question for this post:
the part that says that vlans present security challenges because all users can see all devices on layer 2. I don't get that becuase i thought that vlans broke up broadcast domains and collision. How could computers on seperate vlans see each other?

sorry for all the questions. Im going to take break for couple of days
