Which one is first second and third does not matter , round robin will
shuffle them around anyway.
The "normal way" is to use one as master, the others as slaves. With
a reasonable long expire time you should be able to reconfigure
one of your slaves as master ( and make the remaing slave pull from
the new master) before the zone expires.
All provided that you actually detect the master die before "expire" times out.
