Every slave server needs the following from its masters (whether that's the primary master and/or one or more slaves):

- zone transfer access
- notifications of zone updates

Unless you put in some special and usually unnecessary (and useless) configuration, the notification message has to come from the slave's master, not from the primary master (unless they are the same).
