1、网络拓扑图
2、核心：vrrp知识点
1）虚拟ip地址
vrrp vrid 1 virtual-IP 10.1.1.254
虚拟地址为：10.1.1.254
虚拟mac：0000-5e00-01xx
xx表示组号，此实例中为01
2）虚拟默认优先级为100，范围在0-255
vrrp vrid 1 priority 120
需改优先级为120
3）延时切换，默认时间为0
vrrp vrid 1 preempt-mode timer delay 30
设置延时切换为30s，防止数据丢失，
4）接口跟踪
vrrp vrid 1 track interface GigabitEthernet0/0/5 reduced 30
当跟踪接口出现故障后，优先级值减30，变为90
