AR18系列路由器负载分担的典型配置.doc

AR18系列路由器负载分担的典型配置

一
组网需求：
在很多地区，网吧用户同时申请了中国电信和中国网通两条宽带接入线路，如果此时双线路采用常规的“负载均衡”方式，就会发生访问网通站点走电信线路，访问电信站点走网通线路的情况，由于当前网通和电信两个运营商之间存在着互联互通速度慢的问题，造成速度瓶颈。如何实现“访问网通站点走网通线路，访问电信站点走电信线路”呢？在AR18系列路由器上可以通过配置策略路由的方式满足以上需要。

配置步骤：
1
定义监测组，分别监测电信和网通网关
进入系统视图，创建detect-group 1，监测电信网关：
way>system
Page 4 of 14
System View: return to User View with Ctrl+Z.
[Quidway] detect-group 1
[Quidway-detect-group-1]
[Quidway-detect-group-1]detect-list 1 ip address 61.1.1.1
[Quidway-detect-group-1]quit
创建detect-group 1，监测网通网关：
[Quidway]detect-group 2
[Quidway-detect-group-2]detect-list 1 ip address 202.1.1.1
[Quidway-detect-group-2]quit
[Quidway]
注：以上以地址61.1.1.1最为电信网关地址，地址202.1.1.1为网通网关地址为例，
可以根据实际组网情况修改。
2
配置两条默认路由互为备份，优先走电信线路：
[Quidway]ip route-static 0.0.0.0 0.0.0.0 61.1.1.1 preference 60 detect-group 1
[Quidway]ip route-static 0.0.0.0 0.0.0.0 202.1.1.1 preference 100 detect-group 2
注：以上以地址61.1.1.1最为电信网关地址，地址202.1.1.1为网通网关地址为例，
可以根据实际组网情况修改。

配置静态路由与监测组关联，使访问网通流量优先走网通线路：
以下配置较多，配置过程中可以用实际网通网关地址替换地址202.1.1.1后直接复制粘贴：

注：以上路由已经包含大部分网通地址段，如有更新可以动态添加。
经过如上三个配置步骤后，路由器便能自动区分网通流量和电信流量，使访问网通站点走网通线路，访问电信站点走电信线路。并且当网通线路出问题后所有流量都会自动切换到电信线路上，使用户能够不间断访问网络。

配置关键点：
关键点在于配置缺省路由走电信，精确路由走网通，同时配置一条优先级较低的缺省路由走网通，这样既能实现负载分担，也能实现备份功能
