ROS多条ADSL线路分流

ROS多条ADSL线路分流网络飞速发展的今天，昂贵的光纤租赁费用成就了我国各大营运商，相比廉价的家用ADSL线路来说，非对称的上下行传输，电话线路的信噪干扰导致带宽下降等问题也让ADSL定位成低端产品，光纤固然是好，但是巨大的价格差异下，通过ROS设置多条ADSL为我们更好的服务，节约不少银子。ROS系统是通过网关来区分线路，在很多地区ADSL线路拨号获得的网关是一样的，那么就只有一条线路生效，通过下面的设置让我们把其余的几条一起利用起来吧。Address List阖El IZE回 iAddress/ NetworkBroadcast工nterfmce:3守60.216.158. 11360.216. 158. 11360.216. 158. 113pppoe-out3D令60.216.158. 11360.216.156.10. 0. 0. 0pppoe-out3:1令60. 21& 159. 17360.216.159.17360.216. 159. 173pppoeout1D令60.216.159. 17360.216.156.1 _0. 0. 0. 0pppoeout1:2令124. 133. 116.217124.133.116.124.133.116.217pppoeout2D令124. 133. 116.217124.133.116.10.0.0.0 pppoe-out2令192. 168. 1. 1/24192. 168. 1.0192. 168.1.255LAN 通过这样的设置，就可以睡免其他几条线路的失效，大家注意3条前面带 D的规则，D就是动态的意思，就是说这3条规则是系统拨号获得IP后自动 生成的，另夕卜3条夫见则则是我们手动添加的，给pppoe-outl 2 3都手动添 加上工P，再给施们加上一个comment标姿卩目的是为了让脚本来区分。大家援照如图所示，脚本的目的是来修改我们手动赋值的IP，因为绝大 多数ADSL拨号的IP都是动态的，每次获得IP不一样，我们 不能每次都手 动去修改，剩下的工作就交给脚本去完成了，这就是ROS强大之处。zooyo制作 Route ListxjRoutes Rules+ S HS 回；:3AS0.0. 0.0/060.216.158.113pppoe-out3adsl-3:;:2AS| 0.0. 0 0/0124 133.116.217pppoe-out2adsl-2:;:1AS| 0.0. 0 0/060.216.159 173pppoe-outladsl-lUpU u. u. u/ubU.Zlb.156.11pppoe-outlDJ0.0.0 0/0124.133.116.11pppoe-out2DAp o.o. o.o/o60.216.156.11pppoe-outlDACp 60.216. 156. 160.216. 159. 173pppoe-outlD CF60.216. 156. 160.216.158.113pppoe-out3DACA60.216. 158. 11360.216. 158. 113pppoe-out3DACA 60. 216. 159 17380.216.159.173pppoe-outlDACA 124.133. 116.1124.133.116.217pppoe-out2DACp 124.133. 116.217124.133.116.217pppoe-out2DACp 192. 168. 1.0/24192.168.1.1Distance InterfaceRouting MarkPref.
