RRPP与smart-link & monitor-link联动组网解决方案

实现RRPP与smart-link & monitor-link共存，解决网络二层环路、链路冗余。  

SW1、SW2、SW3交换机构成一个RRPP环，SW1为环的主节点（GI 1/0/1为主端口、GI 1/0/2为副端口）。SW2为环的传输节点（GI 1/0/1为主端口、GI 1/0/2为副端口），SW3为环的传输节点（GI 1/0/1为主端口、GI 1/0/2为副端口）

为了实现二层链路冗余，在SW4交换机配置smart-link组1（GI 1/0/1为主端口，GI 1/0/2为副端口）。

同时为了实现链路故障时能快速切换，分别在SW2、SW3交换机上配置monitor-link组（GI 1/0/1为上行端口，GI 1/0/3为下行端口）。

配置脚本：

SW1：

1、基础配置脚本如下：

 sysname SW1

 router id 1.1.1.1

vlan 10

quit

interface LoopBack0

 ip address 1.1.1.1 255.255.255.255

quit

interface Vlan-interface10

 ip address 192.168.10.254 255.255.255.0

quit

interface GigabitEthernet1/0/1

 port link-mode bridge

 port link-type trunk

 port trunk permit vlan all

 combo enable fiber

 undo stp enable

quit

interface GigabitEthernet1/0/2

 port link-mode bridge

 port link-type trunk

 port trunk permit vlan all

 combo enable fiber

 undo stp enable

quit

 2、关键配置脚本如下：

rrpp domain 1

 control-vlan 4092

 protected-vlan reference-instance 0 to 32

 ring 1 node-mode master primary-port GigabitEthernet1/0/1 secondary-port GigabitEthernet1/0/2 level 0

 ring 1 enable

quit

 rrpp enable

3、状态查看：
