AP 1552E Mesh not fonctionning

[cameroun]

hello, 

I attached to this email architecture to deploy. 
the rukus radio link is operational, and the AP in 1552 that is connected in this building is saved on my WLC. 
I change its role to MeshAP RootAP. I enabled ETHERNET BRIGHING. 

But other AP 1552nd not form the topologies Mesh. Their MAC addresses are already saved in the controller. 

Should I turn on the controller ETHERNET FORWARDING? 

Please I really need help

Have you setup a bridge group yet? You will need a bridge group name to match RAP and MAP's.
