We are are in the process of building a DR site and I was wondering if the following is possible:
We want to have the same vlan defined on two different sites (WAN in between), so if our primary data center is down, services will be virtually moved to a DR site, this way, there is no need to change the ip schema of the servers.
Please see the attached diagram for the details.
So the question is, can we define the same vlan on 2 different sites and move systems that belong to that very same vlan from one site to another.
