Add VRF Support
I want to run a bind instance which listens on a VRF interface. We have all external traffic isolated through VRF and are not able to answer queries on that interface.
Lets say 126.96.36.199 in only available in VRF so the "normal routing/networking stack" does not know that this IP and the routing related to that even exists. Hence the unability of bind9 to listen on those IPs when I want to
listen-on that IP.
I want to be able to
listen-on-v6 to an IP address which is only available on a VRF.
