    Ok, you have to create two wide ip pools. One primairy with the virtual server of the primairy site, one with the DR site virtual server.

    Then in the wide ip select both pools with the primairy site at the top, for load balancing use Global availability.

    The DNS will return the primairy virtual server, the moment it becomes unavailable the DR virtual server will be returned on a query.

Both wide IP pools should contain only 1 ip/record

The primairy the IP/record of the primairy site. The secondary the IP/record of the DR site.

 

Cheers,
