I have magic zone file in my bind 9.7 for three identical zones:
$TTL 86400
@ IN SOA localhost. root.localhost. (
20141010222676
3H ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum
IN NS ns1
IN NS ns2
ns1 IN A 1.2.3.4
ns2 IN A 1.2.3.4
www IN A 10.20.30.40
and this zones in named.conf with single file:
zone "zone1.tld" IN {
type master;
file "zone.tld";
};
zone "zone2.tld" IN {
type master;
file "zone.tld";
};
zone "zone3.tld" IN {
type master;
file "zone.tld";
};
I enable global nsupdate access in named.conf:
allow-update {
key "key_name";
};
after updating via nsupdate any of this zones (e.g. zone1.tld) and stopping
bind I got zone file like this:
$TTL 86400
zone1.tld. IN SOA localhost. root.localhost. (
20141010222676
3H ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum
IN NS ns1
IN NS ns2
ns1 IN A 1.2.3.4
ns2 IN A 1.2.3.4
www IN A 10.20.30.40
zone2 and zone3 is still uses this file as zone, but there is no data in
this file for zone2 and zone3. bind obviously can't start, returning error
"ignoring out-of-zone data".
which is the correct way to maintain several zones with fully identical
data, but with possibility to use nsupdate to it?
