华为eNSP实验:VRRP协议双组双备实验

标签: 华为

一、实验环境

eNSP V100R003C00SPC100版本

二、实验拓扑

在这里插入图片描述

三、实验需求

1,LSW2为192.168.10.0/24网段的主路由,192.168.20.0/24网段的备用路由

2,LSW3为192.168.20.0/24网段的主路由,192.168.10.0/24网段的备用路由

3,当断掉某个网段的主路由时,通过vrrp协议备用路由自动启用。

四、实验步骤

配置PC1,PC2,SW1,SW2,SW3-------在R1上配置回环地址测试---------验证需求

五、验证需求

1,sw2为192.168.10.0/24网段主路由,sw3为192.168.10.0/24网段备用路由
在这里插入图片描述
在这里插入图片描述
用PC1ping测试地址1.1.1.1
分别抓包2台三层交换机的上层口,发现数据在SW2主路由通讯

在这里插入图片描述
左边为SW2上层口,右边为SW3上层口
在这里插入图片描述
2,当断开SW2的上层口时,备用路由SW3会总动变为主路由。SW2变为备用路由。

在这里插入图片描述
分别抓包2台三层交换机的上层口,发现此时数据在原备用路由SW3通讯;
左边为SW2上层口,右边为SW3上层口;
左边此时是静止的,已断开,数据在右边通讯。
