I'm not too familiar with BIND and the way it works. I was wondering if its possible to have one slave to 3-4 master namesevers?
say I have 4 nameservers: north, east, west and south.
East, West and South are masters of the DNS records they carry.
North is a secondary/slave nameservers for ALL 3 master servers, East, West and South.
East, West and South will never carry each other's dns records but North will carry ALL the dns records.
Is this configuration possible?
