BIND主从模式下实现View智能寻线
DNS域名解析基本过程
DNS主从模式下实现VIEW智能寻线
网络拓扑图如下:
实现步骤如下:

4、测试
客户端使用辅助DNS解析:
View会根据客户端IP(172.168.1.10)智能的为其选择匹配的区域文件unicom.soulboy.com.zone(解析地址应为192.168.1.116),结果如下图:
路由器使用辅助DNS解析:
View会根据路由器IP(192.168.1.254)智能的为其选择匹配的区域文件telecom.soulboy.com.zone(解析地址应为192.168.1.106),结果如下图:
至此足可证明主从DNS工作正常,没有问题。
客户端使用辅助DNS解析子域(fin.soulboy.com),结果如下图:
路由器使用复制DNS解析子域(www.fin.soulboy.com),结果如下图:
至此足以证明主从DNS和子域(fin.soulboy.com)工作正常,没有问题。
