我怀疑NetworkManager是如何通过nmclipipe理静态路由的。 我有一个有三个networking接口的CentOS 7.1.1503服务器：
[root@brick ~ ]# nmcli con show NOMBRE UUID TIPO DISPOSITIVO int-ofi-nueva 3646ca3f-42b7-4bef-a677-6f92a5d55ee7 802-3-ethernet enp4s0 tvcable-ext e4dce451-6cc1-4a32-a8d6-394905f6a024 802-3-ethernet enp2s0 int-ofi-vieja ecbb8828-cd46-4b18-8b5e-61291a051553 802-3-ethernet enp5s0 接口enp2s0是我的WAN接口，并且是默认路由的接口。 我已经在接口enp5s0上configuration了一个通过nmcli的静态路由，但是这个路由并没有添加到路由表中，即使在我重新启动NetworkManager之后。 只添加与连接到每个接口的networking对应的路由。 以下是详细信息：

请注意，属性ipv4.routes已设置，但路由未加载。 我必须在连接上设置其他的东西来让内核看到它吗？
