忽略 route-eth0 中的静态路由

Question

为什么 route-eth0 可能会被忽略而 route-eth1 不会？可能是因为 eth0 正在使用 DHCP 而 eth1 是静态配置的？

我配置了一些静态路由

[16:20:06][root@zserver2:/etc/sysconfig/network-scripts]$ ls -al ro*
-rw-r--r-- 1 root root 104 Dec  6 15:49 route-eth0
-rw-r--r-- 1 root root 106 Dec  6 15:49 route-eth1

当我执行 a 时service network restart，eth1 的路由被激活，但不是 eth0 的路由。

Anifup eth0也会忽略它们，但是 anifup-routes eth0就好了。激活它的最佳方法是什么？

Answer 1

这也是我的结论。DHCP i/f 从 DHCP 服务器获取路由信息，因此在这种情况下这些文件将被忽略。

您应该能够通过 NetworkManager 并通过 UI 添加其他路由。
