I understand that to be able to use mGRE tunnels, all that is needed from the AP is to have IP connectivity.  If the AP connects to a port on a switch, and that port is on VLAN 196, for instance, will the following setup allow me to connect to that VLAN over wireless, and at the same time allow other users (through the use of the other SSID) to connect to a network that's on a mobility group?
I've tested it already and it works. I just want to know if there are any drawbacks, or if it's not recommended. etc...
