there's no "default TTL" on recourse records, there's only TTL on resource
records, and the "default TTL" on master server, that uses it for any
resource without explicitly configured TTL.

this does not make sense.

your slave will only forward the update to master. 

Your description does not make sense, what exactly do you want to achieve?
