broadcast domains in Vlans

AkuMa

I can't understand when a router is needed through switches for VLANS ...

1) In one switch if I create some VLANS , I create both collision and broadcast domains per segments , without a router attached ?

2) I only need a router when more than one switch are connected using VLANS ?

hi AkuMa

Router does the job of forwading inter Vlan traffic. It only comes into the picture when traffic is being forwaded between 2 switches.

i hope i am correct.
