bind 9.6.1 CNAME问题

//$ contents of named.conf 完整内容$//
options {
        directory "/var/named/chroot";
        dump-file "/var/named/chroot/data/cache_dump.db";
        statistics-file "/var/named/chroot/data/named_stats.txt";
        pid-file "/var/named/chroot/var/run/named.pid";
};
zone "." {
        type hint;
        file "etc/named.ca";
};
zone "localhost" {
        type master;
        file "etc/local.zone";
};
zone "0.0.127.in-addr.arpa" {
        type master;
        file "etc/127.0.0.zone";
        notify no;
};
zone "example.com" {
        type master;
        file "etc/example.com.zone";
};

//$ contents of example.com.zone $//
x.example.com.                IN        CNAME        x.example0.com.
; example0.com 该dns服务器不是域 ' example0.com ' 的 权威域名服务器。named.conf没有关于该example0.com的配置。
y.example.com.                IN        CNAME        y0.example.com.
y0.example.com.        IN        A                222.222.222.222

1，client：dig @dns_server x.example.com. A
bind 9.2.4 可以成功，bind 9.6.1 却不行。配置文件一模一样。
2，client：dig @dns_server y.example.com. A
bind 9.2.4,bind 9.6.1 都可以成功。

bind 9.6.1 上 在 option 选项里面，加入

        recursion yes;
        additional-from-auth yes;
        additional-from-cache yes;

还是同样的问题。

有遇到相同问题的人吗？

allow-query
Specifies which hosts are allowed to ask ordinary DNS questions. allow-query may also
be specified in the zone statement, in which case it overrides the options allow-query statement.
If not specified, the default is to allow queries from all hosts.
allow-query-cache
Specifies which hosts are allowed to get answers from the cache. If allow-querycache
is not set then allow-recursion is used if set, otherwise allow-query is used if set, otherwise
the default (localnets; localhost is used.
allow-recursion
Specifies which hosts are allowed to make recursive queries through this server. If
allow-recursion is not set then allow-query-cache is used if set, otherwise allow-query is used if
set, otherwise the default (localnets; localhost is used.

recursion 缺省是yes，所以加这个没有用。
可以试试recursion no;

xufengnju

加了

       allow-recursion {any;};

9.6.1就可以工作了。
这两个版本之间确实有这个区别。

谢谢。
