active/active LTM deployment on different subnet
I am thinking about active/active LTM deployment which each LTM is located on different data center and using different subnet. I mean not using GTM at all.
data center A - subnet A
data center B - subnet B
I think if I create VIP on subnet C and D and then configure upstream router to route traffic of subnet C and D to appropriate data center e.g. dynamic route, static route, etc. If one of data center fails, upstream router will be notified and move traffic accordingly.
Is this possible? What do you think?
Has anyone used this configuration?
Thanks a lot!
