I have a 2-server BIND 9 setup. Server A (the 'master' server) is properly setup with two views, one for local DNS clients (allowing recursive lookups for non-authorotive domains) and one view for the rest of the world, allowing only queries for local authorotive domains.

I want to configure the second server (let's name that Server B, or the 'slave' server) a similar way. Unfortunately this does not work properly. Once enabled, any notify from server A will correctly update/transfer the respective zone, but only the 'protected' view will serve the updated information. The 'external' view on server B still returns the 'old' information, until the server is restarted.

One of the tricks here is to ensure that the two zones are transferring from the correct views. If you have zone "" in both the internal and external views, tell the servers to transfer from the internal and external IP addresses as masters (on the slaves) choosing the correct internal/external one for each.

You may also need to explicitly tell BIND to "also-notify" the slave's view(s) as well for each zone.

from bind 9.3 on, you can associate views using TSIG.

Take a look here: How do I share a dynamic zone between multiple views?

Bind 9.10 has a new in-view zone option to say that “this zone I am defining in this view is really the same zone as the one I previously defined in this other view”. This will keep Bind informed that the zones are not separate zones but in reality the same zone.
