Bind Clustering

[Arnoud Tijssen]

We use bind for DNS.
At the moment we have one primary server that delegates updates to it`s two slave servers.

Since everything nowadays is dependant on DNS I would like to cluster my primary server in case of a hardware failure or error.

So, how do I setup two primary bind servers that keep each other in sync one way or the other.
I`ve been surfing the internet, but couldn`t find any satisfactory solution.

Any help is greatly appreciated.
