C. Linux里面查看本机路由表命令是什么

通过netstat命令
netstat命令一直是Linux中打印路由表信息一种广泛使用的方法。然而，它被ip route命令正式取代。无论如何，我们都需要它，因为它仍然是检索所需信息的一种方法。
以下是使用此命令的方法：

$ netstat -rn

如何在Ubuntu中查看网络路由表

-r此标志用于显示内核路由表

-n此标志用于显示数字地址

D. linux如何查看路由表

使用 route 命令可以查看 Linux 内核路由表。

Route命令是用于操作基于内核ip路由表，它的主要作用是创建一个静态路由让指定一个主机或者一个网络通过一个网络接口，如eth0。当使用"add"或者"del"参数时，路由表被修改，如果没有参数，则显示路由表当前的内容。

设置内核路由表的命令格式是：

# route [add|del] [-net|-host] target [netmask Nm] [gw Gw] [[dev] If]

(4)linux查看路由表命令扩展阅读

route命令参数介绍：

-c显示更多信息

-n不解析名字

-v显示详细的处理信息

-F显示发送信息

-C显示路由缓存

-f清除所有网关入口的路由表。

-p与add命令一起使用时使路由具有永久性。
