I am designing a network with two 7220 controllers in one cluster. both controllers are in the same vlan and I configured VRRP between them. I though it would be a good idea to configure LMS-IP to be the virtual VRRP IP address and leave BKP-LMS IP empty, but I found in Aruba documentation they are using controller physical IP address, and not VRRP, for LMS IP. I beleive this is due to the fact that AP will receive node list eventually and will point to this node list, and not LMS IP, but LMS-IP redundancy is needed also.
in my scenario of two controllers only, which option is recommended:
1- LMS IP: VRRP
BKP LMS IP: Empty
2- LMS IP: Controller 1 IP
BKP LMS IP: Controller 2 IP
3- LMS IP: VRRP
BKP LMS IP: Controller 1 or Controller 2
(in case of IP conflict with VRRP IP address)
Thank you
