I think you are not talking about wireless services with roaming. Then, as you can identify your customer with the authentication information and can have a static mapping for customer configurations, you can run multiple DHCP servers without worrying about dynamic state synchronization between the servers. As a malfunctioning anycast server can still advertise a route to it, blocking routes to back up servers, you should not use anycast. Masataka Ohta
