Multi-Site Redundancy

We have an active site and a disaster recovery site and have recently incorporated NSX-T which stretches the L2/L3 domain to both sites. My question is in a DR test our vip can have the same ip address in our active site then it does in our DR site, how can this be accomplished? ive read up on here and disabling ARP in the WPO Virtual Server may be a solution is there another way to accomplish this without using F5 DNS?
