We have multiple internet connections attached to my company's network, from different providers, and there are authoritative name servers on the network as well, also with an IP from each of those networks. The servers have chroot-ed "named" instances, with configurations based on the network.
So Network1 has IP addresses starting with "24.x", while Network2 has IP addresses starting with "96.x". The idea behind the chroot named daemons is that the daemon associated with Network1 will return IP addresses based on that network, while the daemon associated with Network2 will return IP addresses based on its network.
Hopefully that's clear. On to the question.
I want to use RNDC to update zone files and have them propagate to slave name servers on this network. But how do I configure it so that RNDC knows to reload zone files for Network1 when I refer to zone files on that network (and associated chroot-ed environment)...?
