controller A is in building A
controller B is in building B
one more question for L3 mobility. if i associate with AP_a in building A,i will go though controller A to internet....now i am going to building B....i will asoociate another AP_b on building B and the roaming is occured... the whole path is " Controller B -> Controller A -> internet"...Controller B and Controller A will form a mobility tunnel and i don't lose my original IP get from building A. do my concept right?
if the above concept right...but my goal is when i go to building B....i don't want the traffic go back to building A then go to internet. how can i do? so , i dont need mobility , right ? if i don't want lose my original IP...should i need create vlans same as the Building A to do a L2 mobility..???
many thanks,
