<emphasis>Secondary Master</emphasis> is needed in

become unavailable.

+ First, on the Primary Master server, the zone transfer needs to be
allowed. Add the <emphasis>allow-transfer</emphasis>

your Secondary nameserver.

+ Next, on the Secondary Master, install the
<application>bind9</application> package the same way as on the Primary.
+ Then edit the <filename>/etc/bind/named.conf.local</filename> and
add the following declarations for the Forward and Reverse zones:
