3.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

配置SWA：

[SWA]vlan 1 to 30

[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

[SWB-mst-region] instance 1 vlan 1 to 30

[SWB-mst-region] active region-configuration

配置SWC：

[SWC]vlan 1 to 30

[SWC]stp region-configuration

[SWC-mst-region] instance 1 vlan 1 to 30

[SWC-mst-region] active region-configuration

配置SWD：

[SWD]vlan 1 to 30

[SWD]stp region-configuration

[SWD-mst-region] instance 1 vlan 1 to 30

[SWD-mst-region] active region-configuration

步骤三：设置端口类型为TRUNK

分别在端口G1/0/1和G1/0/2上配置物理连接状态up/down抑制时间为0 秒（即不抑制），关闭生成树协议，并将端口配置为 Trunk 端口且允许 VLAN 1～30 通过：

配置SWA：

[SWA]interface GigabitEthernet 1/0/1

[SWA-GigabitEthernet1/0/1]link-delay 0

[SWA-GigabitEthernet1/0/1]undo stp enable

[SWA-GigabitEthernet1/0/1]port link-type trunk

[SWA-GigabitEthernet1/0/1]port trunk permit vlan 1 to 30

[SWA]interface GigabitEthernet 1/0/2

[SWA-GigabitEthernet1/0/2]link-delay 0

[SWA-GigabitEthernet1/0/2]undo stp enable

[SWA-GigabitEthernet1/0/2]port link-type trunk

[SWA-GigabitEthernet1/0/2]port trunk permit vlan 1 to 30

配置SWB：

[SWB]interface GigabitEthernet1/0/1

[SWB-GigabitEthernet1/0/1] port link-mode bridge

[SWB-GigabitEthernet1/0/1] port link-type trunk

[SWB-GigabitEthernet1/0/1] port trunk permit vlan 1 to 30

[SWB-GigabitEthernet1/0/1] link-delay 0

[SWB-GigabitEthernet1/0/1] undo stp enable

[SWB-GigabitEthernet1/0/1]interface GigabitEthernet1/0/2

[SWB-GigabitEthernet1/0/2] port link-mode bridge

[SWB-GigabitEthernet1/0/2] port link-type trunk

[SWB-GigabitEthernet1/0/2] port trunk permit vlan 1 to 30

[SWB-GigabitEthernet1/0/2] link-delay 0

[SWB-GigabitEthernet1/0/2] undo stp enable

配置SWC：

[SWC]interface GigabitEthernet1/0/1

[SWC-GigabitEthernet1/0/1] port link-mode bridge

[SWC-GigabitEthernet1/0/1] port link-type trunk

[SWC-GigabitEthernet1/0/1] port trunk permit vlan 1 to 30

[SWC-GigabitEthernet1/0/1] link-delay 0

[SWC-GigabitEthernet1/0/1] undo stp enable

[SWC-GigabitEthernet1/0/1]interface GigabitEthernet1/0/2

[SWC-GigabitEthernet1/0/2] port link-mode bridge

[SWC-GigabitEthernet1/0/2] port link-type trunk

[SWC-GigabitEthernet1/0/2] port trunk permit vlan 1 to 30

[SWC-GigabitEthernet1/0/2] link-delay 0

[SWC-GigabitEthernet1/0/2] undo stp enable

配置SWD：

[SWD]interface GigabitEthernet1/0/1

[SWD-GigabitEthernet1/0/1] port link-mode bridge

[SWD-GigabitEthernet1/0/1] port link-type trunk

[SWD-GigabitEthernet1/0/1] port trunk permit vlan 1 to 30

[SWD-GigabitEthernet1/0/1] link-delay 0

[SWD-GigabitEthernet1/0/1] undo stp enable

[SWD-GigabitEthernet1/0/1]interface GigabitEthernet1/0/2

[SWD-GigabitEthernet1/0/2] port link-mode bridge

[SWD-GigabitEthernet1/0/2] port link-type trunk

[SWD-GigabitEthernet1/0/2] port trunk permit vlan 1 to 30

[SWD-GigabitEthernet1/0/2] link-delay 0

[SWD-GigabitEthernet1/0/2] undo stp enable

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] 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] 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

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

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]undo RRPP enable

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 detectioln 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。

针对原因①，可以直接查看接口信息：

[SWC]display interface 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 enable

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。

4 思考

1.如果将主节点的主端口关闭，会产生什么现象？

2.此实验中可以有多个控制VLAN吗？
