[knot-dns-users] Master - Slave configuration issues

Hi admin, I found your knot-dns is really amazing software but I have a issue during master & slaves configuration . While I configuring any domain zone in master. The zone details not propagate to slave until and unless I manually specifies the domain name in slave zone. Is there any way to configure this . I hope your reply soon after you receive the email. I'm doing it for my personal use and demo. Regard Innus Ali
