The customer ask me if there is a way to redirect the traffic going to a datacenter to another backup datacenter when the first is not reachable anymore.
I would use the ACE functionality called "cascade Redirect". Is it correct?
I would like to know if there is another way for that.
Another question is:
What method could it use to achieve a DB synchronization with the lowest difference? We have to remember that there are the MPLS VPN and VPN IPSec connections.
Thank you very much.
