華三RRPP實驗(一)

RRPP實驗（一）

目的：掌握RRPP的工做原理及配置；觀察RRPP的報文；

工具：LITO華三模擬器、GNS3模擬器、Wireshark、Ethereal、VM；

說明：由於RRPP的協議報文是二層幀，所以要將華三模擬器LITO橋接到本地VMware的VMnet1，同時在本機（win7）上開啓Wireshark選擇VMnet1抓包。

注：華三模擬器LITO沒法直接將交換機的接口橋接到本地VMware的VMnet1上，需借用GNS3中的交換機與主機來實現。

步驟一：採用LITO搭建拓樸以下

步驟二：打開LITO的安裝路徑(C:\Program Files (x86)\LITO 模擬器\vpcs\lito.liu)，表示本地端口19051與遠程端口19014之間UDP鏈接（SW2的E0/4/1與PC3鏈接）；本地端口19064與遠程端口19053之間UDP鏈接（SW5的E0/4/1與PC4鏈接）。

步驟三：運行GNS3，創建以下拓樸，C1配置詳見下圖

這裏選擇的是VMnet1    

按照步驟二中的端口鏈接進行添加

步驟四：SW1 RRPP Master配置，Sw2 RRPP transit配置

注意：主節點的主端口用來發送探測環路的報文，副端口用來接收該報文。當RRPP環處於健康狀態時，主節點的副端口在邏輯上阻塞數據VLAN，只容許控制VLAN的報文經過；當RRPP環處於斷裂狀態時，主節點的副端口將解除數據VLAN的阻塞狀態，轉發數據VLAN報文；

傳輸節點的主端口和副端口在功能上沒有區別，都用於RRPP環上協議報文和數據報文的傳輸。

步驟五：查看RRPP運行狀態

關閉Sw1的E0/4/0

查看RRPP環的切換

再將SW1的E0/4/0接口開啓

查看RRPP環的恢復

附：在交換機上開啓debug顯示的RRPP Packet信息

下圖是在本機（win7）開啓Wireshark抓包，但沒法顯示RRPP的明細報文種類，應該是wireshark對數據幀的顯示問題。

RRPP有如下幾種報文：

Health

Link-Down

Common-Flush-FDB

Complete-Flush-FDB

Edge-Hello

Major-Fault
