请问主机的路由信息在哪个配置文件呢？

我添加了好几个路由，用route命令只能查看。
具体配置文件在什么地方呢？
谢谢

在linux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

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

3.
redhat
# vi /etc/sysconfig/network-scripts/route-eth0
10.0.0.0/8 via 192.168.0.253
172.0.0.0/8 via 192.168.0.254

debian

# cat /etc/network/interfaces
