I have a simple estate of a Master/Standay,
2 x Locals on Site 1 and 2 X locals on site 2 connected over private fibre.
Currently the HA is done with VRRP and 2 VRID with a Master on each of the locals.
I recently reload one of the controllers and the AP took a while to come back, and if this would have been during the working day, would have impact.
After researching a little, i was thinking of dowing Active:Active with both Locals in Dual mood and still load balance.
Would this mean a GRE tunnel to both locals (primary and backup tunnel) and failover be in the seconds rather than minutes.
Also would moveing to ArubaOS - 8 have more options?
