    Hi,

     

    I have a question to find out the best way to setup the controllers.

     

    There is two master controller in the Branch. I have configured them as Master and Standby master controllers with VRRP and Master Redendancy. AP failover fine between controllers. 

     

    LMS IP is pointing towards VRRP address. 

     

    I have seen also HA Group configuraiton as a sample. I am just wondering,

     

    - What is the Major difference between Master Redendancy and HA group in this setup?

    - Do I have to configure them both? or which on is Aruba approved configuration?

     

    Lateron I would like to add a Controller in Data centre so if both controller fails then AP should go and connect to data centre controller. 

     

    What would be the best approach for this? Having 3 rd LMS IP?

     

    Please guide me.

     

    Thanks,

    Nilay.

    HA is not necessary with master redundancy.  Just make the LMS-IP the VRRP.

     

    If you want to extend the redundancy to the datacenter, just make the  LMS-IP the VRRP and backup LMS-IP the ip address of the datacenter controller. 

     

    That is how you can configure for redundancy on a basic level.

     

    HA configuration would provide additional scenarios detailed here:  http://www.arubanetworks.com/techdocs/ArubaOS_65x_WebHelp/Web_Help_Index.htm#ArubaFrameStyles/VRRP/HighAvOverView.htm%3FTocPath%3DArubaOS%2520User%2520Guide%2520Topics%7CVirtual%2520Router%2520Redundancy%2520Protocol%2520(VRRP)%7C_____1
