I suggest having a look at keepalived: it's significantly simpler.

Why do you care about the query source address?

I don't set any of those options and just let BIND pick whatever source
address it wants; it might choose the server admin address or the
advertised service address, and that doesn't matter because everything
else is configured to accommodate this.
