linux和windows如何添加路由
linux路由的添加对于我们来说很重要，有的时候网络不通，也许就是你路由没加，发出来，希望对大家有所帮助！ 服务器ip(eth0)# ifconfig

输出结果中各个字段的含义是:
Destination表示路由的目标IP地址
Gateway表示网关使用的主机名或者是IP地址。上面输出的"*"表示没有网关
Genmask表示路由的网络掩码
Flags是表示路由的标志。可用的标志及其意义是:U表示路由在启动，H表示target是一台主机，G表示使用网关，R表示对动态路由进行复位设置;D表示动态安装路由，M表示修改路由，!表示拒绝路由。
Metric表示路由的单位开销量
Ref表示依赖本路由现状的其它路由数目
Use表示路由表条目被使用的数目
Iface表示路由所发送的包的目的网络
