前言
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？在华为AR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。
1 路由器连接
第一步：建立本地配置环境，只需将微机（或终端）的串口通过标准RS-232电缆与路由器的Console口连接，如0所示。

通过Console口搭建本地配置环境
第二步：在微机上运行终端仿真程序（Win9X的超级终端等），设置终端通信参数为9600bps、8位数据位、1位停止位、无奇偶校验和无流量控制，并选择终端类型为VT100，如0至0所示。

新建连接

连接端口设置

端口通信参数设置
第三步：路由器上电自检，系统自动进行配置，自检结束后提示用户键入回车，直到出现命令行提示符（如）。
2 负载分担配置指导
2.1 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：
system
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 60.190.80.113
[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 221.12.79.49
[Quidway-detect-group-2]quit
[Quidway]

注：以上以地址60.190.80.113最为电信网关地址，地址221.12.79.49为网通网关地址为例，可以根据实际组网情况修改。
2.2 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 60.190.80.113 preference 60 detect-group 1
[Quidway]ip route-static 0.0.0.0 0.0.0.0 221.12.79.49 preference 100 detect-group 2

注：以上以地址60.190.80.113最为电信网关地址，地址221.12.79.49为网通网关地址为例，可以根据实际组网情况修改。
2.3 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221.12.79.49后直接复制粘贴：
