[c-nsp] Access Point & 2 SSID's Trunked to Vlan's

[Oliver Boehmer (oboehmer)]

Not a wlan expert, but apparently WDS & Fast Secure Roaming
(http://www.cisco.com/en/US/docs/wireless/access_point/12.3_8_JA/configu
ration/guide/s38roamg.html#wp1002608) achieves this.. It's on my to-do
list for my private WLAN :)
