“大v”型网络拓扑结构
非共享网关结构如下图，结构采用小V型，但是每个用户拥有独立的网段，使用不同的网关IP：
非共享网关网络拓扑结构
1.测试准备
1.1设备的选型
本次测试SR/BRAS选择上海贝尔的7750，使用9.0R7的软件版本。
交换机采用华为9312产品，OLT分别采用华为和阿朗的设备。
（阿朗OLT不具备测试条件，配置方法可以参考佛山公司的测试结果）

2.测试方法
2.1“小V”专线业务热备测试
2.1.1设备配置
热备配置方式：
小V型组网采用SRRP+LACP的方式，SR和SW之间启用LACP检测传输链路状态，2台SR之前启用SRRP同步信息
路由发布配置：
由于SRRP协议的主备用端口都是UP，主备SR同时发布路由，因此对于用户下行流量，会同时下发到主备用SR，流量到达备用的SR后，通过redundant-interface送回到主用SR，如下图所示：
这样会导致备用侧的上下行重复流量，无形中导致可用带宽变小，因此，必须抑制备用侧发布路由，由于7750启用SRRP后，会产生srrp-master和srrp-non-master两种类型的路由，备用侧只要抑制srrp-non-master类型的路由就可以了。

测试项目
小“v”型专线业务热备测试
测试目的
验证专线业务备份功能，在链路中断时，业务得到保护的情况
测试环境
测试步骤
1、在SW接终端分别ping网关和外网（XX）
2、中断链路1，观察业务情况。
3、恢复链路1，观察业务情况
预期结果
主用链路1出现故障，业务可以正常切换到备用侧
测试结果
ping网关

ping外网由于涉及到主备SR用户路由的发布切换，因为中断时间会稍长
