  • 1.  mobility between two controller cluster

    Posted Dec 11, 2013 11:17 PM


    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..

    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

    or am i way off?

    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,

    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.

    the <hat agent ip> should be in the loacl controllers which under the same master controller???

     

    thx a lot..
