前言
vrrp 漂移网关地址，根据优先级来
vrrp 可以用在思科，还可用在华为
思科的PVST+就是双组双备————HSRP
文章目录
- 一：先进行配置
- 二：测试验证
- 2.1 给pc机设置ip地址
- 2.2 对两个上连口抓包
- 2.2.1 pc1（192.168.10.100）去ping1.1.1.1 ，在lsw1抓到包
- 2.2.2 pc2（192.168.20.100）去ping 1.1.1.1，在lsw2抓到数据包
- 2.2.3 查看路由表
- 2.3 然后把lsw1的上连口g 0/0/1断掉测试
- 2.4 在LSW11下连口g0/0/2开启抓包，开启LSW1的g0/0/1接口，然后再查看vrrp
- 2.5 然后关闭LSW1下连口g 0/0/2，进行测试
一：先进行配置

2.4 在LSW11下连口g0/0/2开启抓包，开启LSW1的g0/0/1接口，然后再查看vrrp
2.4.1 发现在下连口的vrrp协议数据开始交互
2.4.1 查看vrrp
之前的vrrp
- lsw1的vrrp为 ————vlanif10 backup vlanif20 backup
- lsw2的vrrp为 ————vlanif10 master vlanif20 master
现在的vrrp
- lsw1的vrrp为 ————vlanif10 master vlanif20 backup
- lsw2的vrrp为 ————vlanif10 backup vlanif20 master
自动恢复正常

2.5.3 pc1 去ping 1.1.1.1
可以发现链接超时，数据包从右边LSW2（此时vrrp为master）进路由器，然后从左边LSW1出
因为AR1浮动路由并未启用，导致超时，通向192.168.10.0的路由条目的下一跳为11.0.0.2（LSW1的g0/0/1口）
2.5.4 pc2 去ping 1.1.1.1
不变
后面会再进行优化，解决这个问题
