Master Controller Redundancy across multiple data centres

  • 1.  Master Controller Redundancy across multiple data centres

    Posted Apr 30, 2013 12:12 PM

    Hello,

     

    The Aruba design guides recommend VRRP or LMS between controller pairs for failover.

     

    I am hoping to split my local and master controller pairs across two data centres. The LMS feature will allow me to failover between the local WLCs because it is a layer 3 process.

     

    The design guides only recommend using VRRP for the master controller pair. This is slightly challenging across multiple data centres due to the layer 2 link required. What is the best way to achieve master controller failover? You could configure a layer 2 tunnel between the data centres but I am hoping there is a simpler way.

     

    Thanks

     I think that if you have layer 3 setup between master you will need to setup a GRE tunnel

    Thank you - the GRE looks like the answer
