## 实验过程

### 实验任务一：RRPP单环配置

**本实验任务主要是通过RRPP协议解决二层网络环路问题，；RRPP 是专门应用于以太网环的链路层协议，具有比生成树协议更快的收敛速度，当以太网环完整时它能够防止数据环路引起的广播风暴，且收敛时间与环网上节点数无关，可应用于网络直径较大的网络**

#### 步骤一：基本配置

**按照图1搭建实验环境，给设备改名，根据表1为所有设备配置相应VLAN，配置参考基本实验配置。**

#### 步骤二：创建MST域

**[SWA]stp region-configuration**

**[SWA-mst-region]instance 1 vlan 1 to 30**

**[SWA-mst-region]active region-configuration**

**配置SWB：**

**[SWB]vlan 1 to 30**

**[SWB]stp region-configuration**

#### 步骤四：创建 RRPP 域

**将 VLAN 4092 配置为该域的主控制 VLAN，并将 MSTI 1 所映射的 VLAN 配置 为该域的保护 VLAN；**

**配置本设备为主环Ring 1的主节点，主端口为G1/0/1，副端口为G1/0/2， 并开启该环，配置子环Ring 2的辅助边缘节点，边缘端口为Ethernet1/0/3，并使能该环。**

**配置SWA：**

### 实验任务二：主节点收不到Hello报文排错

#### 步骤一：把SWC关闭RRPP协议

**在SWC上配置：**

**[SWC-rrpp-domain1] control-vlan 4093**

#### 步骤二：故障分析及信息收集

**在SWC上查看运行情况：**

<**SWA**>**display rrpp verbose domain 1**

**Domain ID : 1**

**Control VLAN : Primary 4092, Secondary 4093**

**Protected VLAN: Reference instance 1**

**Hello timer : 1 seconds, Fail timer: 3 seconds**

**Fast detection status: Disabled**

**Fast-Hello timer: 20 ms, Fast-Fail timer: 60 ms**

**Fast-Edge-Hello timer: 10 ms, Fast-Edge-Fail timer: 30 ms**

**Ring ID : 1**

**Ring level : 0**

**Node mode : Master**

**Ring state : Failed**

**Enable status : Yes, Active status: Yes**

**Primary port : GE1/0/1 Port status: UP**

**Secondary port: GE1/0/2 Port status: UP**

**发现主端口与副端口同时打开，那么可能有两个原因：**

**端口处于非正常状态；**

**RRPP环上有节点没有开启RRPP协议。**

**在同一RRPP环上的节点的域ID或控制VLAN ID不同**

**针对原因3，可以直接查看控制VLAN ID信息：**

**[SWC]display RRPP brief**

**Brief information on interfaces in route mode:**

**Link: ADM - administratively down; Stby - standby**

**Protocol: (s) - spoofing**

**Interface Link Protocol Primary IP Description**

**InLoop0 UP UP(s) --**

**MGE0/0/0 DOWN DOWN --**

**NULL0 UP UP(s) --**

**REG0 UP -- --**

**Brief information on interfaces in bridge mode:**

**Link: ADM - administratively down; Stby - standby**

**Speed: (a) - auto**

**Duplex: (a)/A - auto; H - half; F - full**

**Type: A - access; T - trunk; H - hybrid**

**Interface Link Speed Duplex Type PVID Description**

**FGE1/0/53 DOWN 40G A A 1**

**FGE1/0/54 DOWN 40G A A 1**

**GE1/0/1 UP 1G(a) F(a) T 1**

**GE1/0/2 UP 1G(a) F(a) T 1**

**发现SWC物理端口正常，其他设备同此操作；**

**在SWC也通过命令display rrpp statistics domain 1查看状态信息：**

**[SWC]display rrpp statistics domain 1**

**Ring ID : 1**

**Ring level : 0**

**Node mode : Transit**

**Active status : No**

**Primary port : GE1/0/1**

**Fast-Hello packets: 0 Sent, 0 Received**

**Fast-Edge-Hello packets: 0 Sent, 0 Received**

**Direct Hello Link Common Complete Edge Major Total**

**down flush FDB flush FDB hello fault**

-**-------------------------------------------------------------------------**

**Out 0 0 0 0 0 0 0**

**In 0 0 0 0 0 0 0**

**Secondary port: GE1/0/2**

**Fast-Hello packets: 0 Sent, 0 Received**

**Fast-Edge-Hello packets: 0 Sent, 0 Received**

**Direct Hello Link Common Complete Edge Major Total**

**down flush FDB flush FDB hello fault**

-**-------------------------------------------------------------------------**

**Out 0 0 0 0 0 0 0**

**In 0 0 0 0 0 0 0**

**发现SWC的Active status为No，因此判断为RRPP协议未开启。**

#### 步骤三：故障排除

**在SWC上配置：**

**[SWC-rrpp-domain1] control-vlan 4092**

**观察RTC的IP路由表：**

**[SWC]display rrpp statistics domain 1**

**Ring ID : 1**

**Ring level : 0**

**Node mode : Transit**

**Active status : Yes**

**Primary port : GE1/0/1**

**发现SWC的Active status 为 Yes，故障排除。**

**[SWE-Ethernet1/0/2] port trunk permit vlan 1 to 30**

**[SWE-Ethernet1/0/2] quit**

#### 步骤四：创建 RRPP 域

**将 VLAN 4092 配置为该域的主控制 VLAN，并将 MSTI 1 所映射的 VLAN 配置 为该域的保护 VLAN；**

**配置SWA：**

**[SWA] rrpp enable**

**[SWA] rrpp domain 1**

**[SWA-rrpp-domain1] control-vlan 4092**

**[SWA-rrpp-domain1] protected-vlan reference-instance 1**

**[SWA-rrpp-domain1] ring 1 node-mode master primary-port GigabitEthernet 1/0/1 secondary-port GigabitEthernet 1/0/2 level 0**

**[SWA-rrpp-domain1] ring 1 enable**

**[SWA-rrpp-domain1] quit**

**配置SWB：**

**[SWB] rrpp enable**

**[SWB]rrpp domain 1**

**[SWB-rrpp-domain1] control-vlan 4092**

**[SWB-rrpp-domain1] protected-vlan reference-instance 1**

**[SWB-rrpp-domain1]ring 1 node-mode transit primary-port GigabitEthernet1/0/1 secondary-port GigabitEthernet1/0/2 level 0**

**[SWB-rrpp-domain1] ring 1 enable**

**[SWB-rrpp-domain1] ring 2 node-mode edge edge-port ethernet 1/0/3**

**[SWB-rrpp-domain1] ring 2 enable**

**[SWB-rrpp-domain1] quit**

**配置SWC：**

**[SWC] rrpp enable**

**[SWC]rrpp domain 1**

**[SWC-rrpp-domain1] control-vlan 4092**

**[SWC-rrpp-domain1] protected-vlan reference-instance 1**

**[SWC-rrpp-domain1]ring 1 node-mode transit primary-port GigabitEthernet1/0/1 secondary-port GigabitEthernet1/0/2 level 0**

**[SWC-rrpp-domain1] ring 1 enable**

**[SWC-rrpp-domain1] ring 2 node-mode assistant-edge edge-port ethernet 1/0/3**

**[SWC-rrpp-domain1] ring 2 enable**

**[SWC-rrpp-domain1] quit**

**配置SWD：**

**[SWD] rrpp enable**

**[SWD]rrpp domain 1**

**[SWD-rrpp-domain1] control-vlan 4092**

**[SWD-rrpp-domain1] protected-vlan reference-instance 1**

**[SWD-rrpp-domain1]ring 1 node-mode transit primary-port GigabitEthernet1/0/1 secondary-port GigabitEthernet1/0/2 level 0**

**[SWD-rrpp-domain1] ring 1 enable**

**[SWD-rrpp-domain1] quit**

**配置SWE：**

**[SWE] rrpp domain 1**

**[SWE-rrpp-domain1] control-vlan 4092**

**[SWE-rrpp-domain1] protected-vlan reference-instance 1**

**[SWE-rrpp-domain1] ring 2 node-mode master primary-port ethernet 1/0/1 secondary-port ethernet 1/0/2 level 1**

**[SWE-rrpp-domain1] ring 2 enable**

**[SWE-rrpp-domain1] quit**

**[SWE] rrpp enable**

#### 步骤五：显示RRPP运行情况

**配置完成后，用户可以使用 display 命令显示各设备上 RRPP 的配置和运行情况**

**[SWA]display rrpp statistics domain 1**

**Ring ID : 1**

**Ring level : 0**

**Node mode : Master**

### 实验任务二：主节点收不到Hello报文排错

#### 步骤一：把SWC关闭RRPP协议

**在SWC上配置：**

**[SWC-rrpp-domain1] control-vlan 4093**

#### 步骤二：故障分析及信息收集

**在SWC上查看运行情况：**

<**SWA**>**display rrpp verbose domain 1**

**Domain ID : 1**

**Control VLAN : Primary 4092, Secondary 4093**

**Protected VLAN: Reference instance 1**

**Hello timer : 1 seconds, Fail timer: 3 seconds**

**Fast detection status: Disabled**

**Fast-Hello timer: 20 ms, Fast-Fail timer: 60 ms**

**Fast-Edge-Hello timer: 10 ms, Fast-Edge-Fail timer: 30 ms**

**Ring ID : 1**

**Ring level : 0**

**Node mode : Master**

**Ring state : Failed**

**Enable status : Yes, Active status: Yes**

**Primary port : GE1/0/1 Port status: UP**

**Secondary port: GE1/0/2 Port status: UP**

**发现主端口与副端口同时打开，那么可能有两个原因：**

**端口处于非正常状态；**

**RRPP环上有节点没有开启RRPP协议。**

**在同一RRPP环上的节点的域ID或控制VLAN ID不同**

**针对原因3，可以直接查看控制VLAN ID信息：**

**[SWC]display RRPP brief**

**Brief information on interfaces in route mode:**

**Link: ADM - administratively down; Stby - standby**

**Protocol: (s) - spoofing**

**Interface Link Protocol Primary IP Description**

**InLoop0 UP UP(s) --**

**MGE0/0/0 DOWN DOWN --**

**NULL0 UP UP(s) --**

**REG0 UP -- --**

**Brief information on interfaces in bridge mode:**

**Link: ADM - administratively down; Stby - standby**

**Speed: (a) - auto**

**Duplex: (a)/A - auto; H - half; F - full**

**Type: A - access; T - trunk; H - hybrid**

**Interface Link Speed Duplex Type PVID Description**

**FGE1/0/53 DOWN 40G A A 1**

**FGE1/0/54 DOWN 40G A A 1**

**GE1/0/1 UP 1G(a) F(a) T 1**

**GE1/0/2 UP 1G(a) F(a) T 1**

**发现SWC物理端口正常，其他设备同此操作；**

**在SWC也通过命令display rrpp statistics domain 1查看状态信息：**

**[SWC]display rrpp statistics domain 1**

**Ring ID : 1**

**Ring level : 0**

**Node mode : Transit**

**Active status : No**

**Primary port : GE1/0/1**

**Fast-Hello packets: 0 Sent, 0 Received**

**Fast-Edge-Hello packets: 0 Sent, 0 Received**

**Direct Hello Link Common Complete Edge Major Total**

**down flush FDB flush FDB hello fault**

-**-------------------------------------------------------------------------**

**Out 0 0 0 0 0 0 0**

**In 0 0 0 0 0 0 0**

**Secondary port: GE1/0/2**

**Fast-Hello packets: 0 Sent, 0 Received**

**Fast-Edge-Hello packets: 0 Sent, 0 Received**

**Direct Hello Link Common Complete Edge Major Total**

**down flush FDB flush FDB hello fault**

-**-------------------------------------------------------------------------**

**Out 0 0 0 0 0 0 0**

**In 0 0 0 0 0 0 0**

**发现SWC的Active status为No，因此判断为RRPP协议未开启。**

#### 步骤三：故障排除

**在SWC上配置：**

**[SWC-rrpp-domain1] control-vlan 4092**

**观察RTC的IP路由表：**

**[SWC]display rrpp statistics domain 1**

**Ring ID : 1**

**Ring level : 0**

**Node mode : Transit**

**Active status : Yes**

**Primary port : GE1/0/1**

**发现SWC的Active status 为 Yes，故障排除。**
