在windows服务器添加一条静态路由的方法
1、添加一条路由表
route add 60.232.142.25 mask 255.255.255.248 192.168.100.250 metric 3 if 2
添加一条路由记录，所有到60.232.142.25/29网段的数据包，都通过2号网络接口卡走192.168.100.250的网关，优先级为3。

route add –p 60.232.142.25 mask 255.255.255.248 192.168.100.250 metric 3 if 2
作用同上，只是这是一条长久路由，不会因为重启机器而丢失。

2、删除一条路由表
route delete 60.232.142.25
route delete 60.232.*
请留心：如果有两条路由记录有着相同的“目的网络号”，则会将两条记录同时删除。如果只想删除其中某一条的话，请在删除后用route add命令再添加上其中一条。

3、修改一条路由记录
route change 157.0.0.0 mask 255.0.0.0 157.55.80.254 metric 2 if 2
change参数只能修改“网关”和“跳数”

---------------------
linux下添加路由的方法：
一：使用 route 命令添加使用route 命令添加的路由，机器重启或者网卡重启后路由就失效了。
//添加到主机的路由
# route add –host 192.168.168.110 dev eth0
# route add –host 192.168.168.119 gw 192.168.168.1

//添加到网络的路由
# route add –net IP netmask MASK eth0
# route add –net IP netmask MASK gw IP
# route add –net IP/24 eth1

//添加默认网关
# route add default gw IP

//删除路由
# route del –host 192.168.168.110 dev eth0
route add -net 192.168.9.253 netmask 255.255.255.255 gw 192.168.31.254

在linux服务器下设置永久路由的方法：
1.在/etc/rc.local里添加方法：
route add -net 192.168.3.0/24 dev eth0
route add -net 192.168.2.0/24 gw 192.168.3.254
route add -net 192.168.34.0/24 gw 192.168.31.254

2.在/etc/sysconfig/network里添加到末尾
方法：GATEWAY=gw-ip 或者 GATEWAY=gw-dev

3./etc/sysconfig/static-router :
any net x.x.x.x/24 gw y.y.y.y

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。
