I got a cisco switch and a cisco router and I'm going to configure 3 vlans. Making fa0/1 to 3 subinterfaces 0.1, 0.2 and 0.3. I have put in ip adresses on these. I have a switch where there are 3 pc's attached via fa connections. These are on different vlans. encapsulation on the router are dot1q 1 native, dot1q 2 and dot1q 3 on the different subinterfaces. The router and switch are connected via fa0/1. How do I set up the vtp, vlan and trunking to get this to work? Anybody with a good walkthrough?
