    Currently there is no mechanism to failover public (or PSN) IP addresses between vDCs, to redirect traffic between 2 vDCs in a DR failover situation. Global Site Selection via DNS or manual DNS changes could be used to redirect traffic between 2 vDCs with different public IPs, but these options do have limitations (DNS caching etc).

    It would be useful to be able to advertise the same IP address/range from 2 different vDCs with BGP preferences plus interface tracking or health checks used to identify the preferred site and update the routing accordingly.
