Very good Ralph. I will have a go at this on my lab tommorow. Will be interesting what I run into.
I will post my findings here. regards.

My VLAN config is in the WLAN20native-WPA-RootAP.txt file. I did 4 scenarios this evening. 1. Simple root ap with repeater ap all on native vlan 1 and bridge-group1. I attached the 2 configs. Simple-WPA. This is as I see it as vanilla as it gets. And it works perfectly. 2. Same config but the Root AP now has bridge group 20 assigned to the d0 interface and fas0.20 interface. Fa0.20 is dot1q vlan 20. I have attached the 2 files. (BridgeG20-d0-WPA). This also works but I did have to reboot the root-ap as the mac of the laptop client was stuck in bridge 1 mac table. 3. The ssid on the root ap now has a VLAN 20 assigned to it and the bridge-group 20 has been moved to interface d0.20. d0.20 is encap dot1 20 native. The Repeater AP and the client can associate with the Root AP and get full IP traffic to VLAN 20. But when the client connects to the Repeater AP it never gets an IP. The laptop client is simply not seen as a dot11 association on the root ap. (Config VLAN20native) 4. This is the funny part. My saved config from step 2 is now copied into the startup-config on both AP's and they are reloaded. They come up again and now it doesn't work. Reload the laptop, try another. Nope just don't work. Start pinging from the Repeater AP BVI1 to the Default Gateway in VLAN 20, and that works fine. 30 seconds later the laptop gets an IP. So my note being..... you need luck... :o) /Ralph 2011/1/31 Kristján Ólafur Eðvarðsson <[email protected]>: > I would be interesting to post your configurations for this. > I remember having this at Bootcamp and made it work.
