Hi
I try to configure GRE tunnel for guest traffic from instant cluster to a controller located in central location.
There is a plan to deploy a lot of instant clutser in different geographic location and to tunnel only guest traffic to central controller/controllers.
I would like to deploy only one tunnel from each instant cluster to central controller not a tunnel for each IAP, because there would be a thousands of IAP.
I have confugred IAPs and controller according to documents I have found on community:
http://community.arubanetworks.com/t5/Wireless-Access/Tutorial-Guest-only-solution-using-IAP-GRE-tunnel-with/td-p/147880
http://community.arubanetworks.com/t5/Controller-less-WLANs/Manual-GRE-between-IAP-amp-controller-to-use-L2-centralzed-scope/ta-p/291890
I have configured solution with DHCP scope L2 centralized and with manual GRE tunnel and option Per-AP tunnel disabled (so to pass trafic only via master virtual-controller) .
It works but only when Wifi client connects to master VC, when client assiciates with other APs, then client cannot get IP address from DHCP (defined on central controler).
So my question is
1) Is it possible to have only one GRE tunnel for each Instant cluster ?
2) If yes what should I do to pass traffic via Master VC ? In above docs theres no information about that (or I'm missing something)
Any other help and advices would be very appraciated.
