i have two aruba controller cluster in two differnet building. both two cluster are in Master/Local(active/passive) model.now these two builging are connect to a large building, so we have a project to set a roaming between this two cluster controller.(from buliding A to building B and vise)as there are two different clients subnet on each side, so i need to enable the L3-mobility between these two cluster ?or do i add the same building A vlans on controllers to building B controllers to do a L2 mobility??
what is my decision should i concern or care about on ?which mobility model should i perfrom??all help are very appreciate..arubafresher
Since you have two different Master-local clusters, I would enable L3 mobility for these clients.
Can you give a deeper explanation, Seth?
I would configure L3 roaming (IP Mobility) between these buildings vs. adding VLANs to both sides. This is covered in our user guide but a basic config (in 6.3) would look like this...
ip mobile domain CampusXYZ
hat 172.16.100.100 description "Bldg1 ihome agent"
hat 192.168.100.100 description "Bldg 2 home agent"
Right. but he does not define VRRP. souldnt he have that first? :)
or am i way off?
edit: nwm. he does. sorry :fool's errand)
YOu don't need VRRP between these buildings
nahh . not between the buildings. just in the cluster.
dear Seth Fiermonti,,
many thanks for soon reply...
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..???
any limitation of the l3 mobility between two controller? my controller model is 7200 series...
how many concurrent roaming user/serssion support?? assume that my building at most 5000 people will use wifi and walk across two building...
There wont be 5000 users roaming :) I think you will be good to go.
hi Seth R. Fiermonti
the <hat agent ip> should be in the loacl controllers which under the same master controller???
thx a lot..
