Can the controller support Master - Master Redundancy across the Layer3 routing?
1) Active Master - Active Master
2) Active Master - Backup Master
and is this support the centralized license?
Master#1 - IP 172.16.10.1 ------------------WAN---------------- Master#2 IP 192.168.20.1

Do you mean AP fast failover?
If Yes, What do I have to do about the vlan on both active controller and backup controller?
Can it be on the different subnet for the user-vlan id?
- SSID-XXX, Tunnel mode, VLAN10
- SSID-XXX, Tunnel mode, VLAN20

Active Controller#1 (18AP attached), Dual
Active Controller#2 (20AP attached), Dual
Active Controller#3 (13AP attached), Dual
Active Controller#4 (0AP attached), Dual (64 Support AP)
Active Controller#5 (0AP attached), Dual (64 Support AP)
1)What the result if #1 ,#2 and #3 controllers are fail ?
2)Should I make #5 as the standby controller?
Thanks again for your help.

If multiple controllers fail, you can leverage backup LMS failover.
Please work with your Aruba or partner SE. There are other considerations in a multi-controller environment. We don't know anything about your network.

Thanks for your advise, I will contact the Aruba Partner.
And I have one question
ControllerA - Active (Terminates 30APs)
ControllerB - Active (Terminates 0 AP)
ControllerC - Standby (Terminates 0 AP)
If I had HA with N:1 (many active controllers : 1 backup controller)
Can I configure backup LMS in the AP system profile to ControllerB in the case when the ControllerC failed?
"HA takes precedence over LMS"
Please explain and correct me. Thanks a lot
