Each BIND instance is a "master", DLZ-backed by a multi-master, fast-replication datastore (such as a directory) will give you what you want, and many have made this work. You will need to do some building (the zone management piece) and some tuning (pessimal performance until you make it yours, heavy toll from attempting IXFR from it). You'll need to understand DNS, BIND, your datastore technology and some of the caveats of multimaster replication, including preventing race-condition and granular resource locking, as well as inter-box semaphores.

DLZ is a mechanism by which it could be done, but as far as I'm aware no one has done it. You'd need a database that did active data replication on the backend, and a DLZ driver for that database which supported dynamic updates. (The DLZ API introduced in BIND 9.8 has support for those, but most existing DLZ drivers are still using the older API.) I wouldn't want to do it that way, though; DLZ's too slow. -- Evan Hunt -- e...@isc.org Internet Systems Consortium, Inc. _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users ----- No virus found in this message.
