RRPP实验（一）
目的：掌握RRPP的工作原理及配置；观察RRPP的报文；
工具：LITO华三模拟器、GNS3模拟器、Wireshark、Ethereal、VM；
说明：因为RRPP的协议报文是二层帧，因此要将华三模拟器LITO桥接到本地VMware的VMnet1，同时在本机（win7）上开启Wireshark选择VMnet1抓包。
注：华三模拟器LITO无法直接将交换机的接口桥接到本地VMware的VMnet1上，需借用GNS3中的交换机与主机来实现。
步骤一：采用LITO搭建拓朴如下
步骤二：打开LITO的安装路径(C:\Program Files (x86)\LITO 模拟器\vpcs\lito.liu)，表示本地端口19051与远程端口19014之间UDP连接（SW2的E0/4/1与PC3连接）；本地端口19064与远程端口19053之间UDP连接（SW5的E0/4/1与PC4连接）。
步骤三：运行GNS3，建立如下拓朴，C1配置详见下图
这里选择的是VMnet1
按照步骤二中的端口连接进行添加
步骤四：SW1 RRPP Master配置，Sw2 RRPP transit配置

注意：主节点的主端口用来发送探测环路的报文，副端口用来接收该报文。当RRPP环处于健康状态时，主节点的副端口在逻辑上阻塞数据VLAN，只允许控制VLAN的报文通过；当RRPP环处于断裂状态时，主节点的副端口将解除数据VLAN的阻塞状态，转发数据VLAN报文；
传输节点的主端口和副端口在功能上没有区别，都用于RRPP环上协议报文和数据报文的传输。
步骤五：查看RRPP运行状态
关闭Sw1的E0/4/0
查看RRPP环的切换
再将SW1的E0/4/0接口开启
查看RRPP环的恢复
附：在交换机上开启debug显示的RRPP Packet信息

下图是在本机（win7）开启Wireshark抓包，但无法显示RRPP的明细报文种类，应该是wireshark对数据帧的显示问题。
RRPP有以下几种报文：
Health
Link-Down
Common-Flush-FDB
Complete-Flush-FDB
Edge-Hello
Major-Fault
