mobility between two controller cluster

[ Edited ]


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..

Re: mobility between two controller cluster

Since you have two different Master-local clusters, I would enable L3 mobility for these clients.

Re: mobility between two controller cluster

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

   description <description>

   hat 172.16.100.100 description "Bldg1 ihome agent"

   hat 192.168.100.100 description "Bldg 2 home agent"

Re: mobility between two controller 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..???

 

many thanks,
