1. 前言

2. 测试网络的物理拓扑

测试采用网络拓扑与现网的设备是密切相关的。既考虑到网络的现状，也要考虑未来的网络结构的演进和变化，本次测试设计到两个类型的拓扑图。

“小v”型结构如下图， OLT到SW的上联链路进行捆绑（快速LACP），7750和SW直接使用EFM功能防止单通，SR之间的采用SRRP实现专线业务的热备，。

本次测试SR/BRAS选择上海贝尔的 7750，使用9.0 R7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）

4.1 “小V”专线业务热备测试

4.1.1 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。

4.3 非共享网关专线业务热备测试

4.3.1 设备配置

热备配置方式：

非共享网关采用主备SR之间启用eth-OAM协议，OAM协议通过SW透传的方式实现，主用SR只发不收OAM报文，备用SR只收不发OAM报文，当备用SR收到错误的eth-OAM报文，将会把OAM报文丢弃，同时把关联的sap设置为down。备用的对应逻辑端口是down的，主备配置相同的网关IP，备用侧绑定主用侧网关的MAC地址，如下图：

7750UpEth-OAM主用侧发送OAM报文LACPLACP7750DownEth-OAM备用侧只接收OAM报文由于remote-mepid未设置，因此sap点是down的

当主用侧链路中断时，由于LACP检测不到报文，使得主用SR的sap点down，备用SR将接收不到主用SR发出的eth-OAM报文，sap点状态变为UP，同时路由由备用侧发布，实现主备切换路由发布配置：

由于备用SR的用户逻辑端口是down的，因此不存在主备用同时发布用户路由问题，如下图所示：

4.4 城域网路由组织优化

现网配置路由发布设置：

主备SR均设置发布用户明细路由，备用侧用户端口down，如下图：

－47－

城域网与OLT配合采用

VRRP测试方案

存在问题：

SR和CR都存在大量的32位用户路由，随着业务量的发展，路由表将急剧扩张。降低设备性能

路由优化方案 SR路由接收优化：

SR只接收CR发布的BGP默认路由，过滤其他明细路由（金万邦等用户需要接收移动明细路由，对应的SR可以接收CR的聚合路由） SR路由发布优化：

? 启用SRRP热备架构后，可以通过SRRP策略控制主备SR的路由发布 ? 现网一般以25位网段确定主备关系，主用SR发布25位exact路由，备用SR发布srrp-master路由，不发布25位路由如下图：
