In $primary:/etc/bind/named.conf.local:

zone "purple.com" {
     type master;
     file "purple.com";
     also-notify { $secondary; $tertiary;};
};

In $secondary & $tertiary:/etc/bind/named.conf.local:

zone "purple.com" {
      type slave;
      masters { $primary; };
      file "purple.com";
};

The also-notify {} and masters {} strings must be IP's, not hostnames.

Now when you update DNS on $primary, $secondary and $tertiary will pick
it up almost immediately.
