It becomes tricky for DHCP if a location has the same cost to more than

datacenters using different local-preferences to simulate a failover
active/passive setup.

The relay server `dhcplb` could, maybe, help in that scenario (dhcplb runs on the anycast IP, the “real” DHCP servers on unicast IPs behind dhcplb).
