LinuxQuestions.org - NSD zone XFR error "NOT IMPL"

I have a master/slave nsd setup and am testing the zone transfer. When I issue

Code:

nsd-control notify example.net

nsd-control notify 3.168.192.in-addr.arpa.

I receive an error message.

Code:

Aug  4 16:47:11 ns2 nsd[22095]: xfrd: zone example.net received error code NOT IMPL from 192.168.3.22
