I found an error in my post about private VLANS in the picture of the traffic flow. PC’s that are located in the same community VLAN do have forwarding at layer 2 without going through a router. I have updated the picture to show the correct traffic flow. I always try to keep my posts as correct as possible but it is impossible to always be 100% correct. If you do find any errors please post a comment so that I am aware of it. If you are interested in private VLANs there is a RFC about it, RFC 5517. You can find it here.
