BIND Slave 收到来自其他 Slave 的通知？

Question

我也有一个主名称服务器设置和几个从站。今天，当我遇到一条奇怪的错误消息时，我正在将其中一个从属服务器更改为新服务器。
在主服务器上更新 DNS 记录并重新启动 BIND 后，我注意到它ns3.mydomain.com正在尝试发送ns4.mydomain.com通知。我检查的配置文件，并没有在那里它拥有的IP地址ns4.mydomain.com的ns3.mydomain.com配置文件。
它不应该ns1.mydomain.com将通知发送给ns4而不是ns3吗？我还要指出，双方的DNS记录ns3，并ns4似乎被更新。

这是 ns3 上的错误消息（IP 地址：）107.161.xxx.xxx：

如果您不想发送通知消息，请notify master-only;在该options部分中指定或notify no;在从属zone定义中指定。

Notify 消息默认发送到所有区域的名称服务器（基于NS区域数据中的记录），除了SOA MNAME（另见notify-to-soa）。
