switch1(config-if)# vrrp 2 preempt
switch1(config-if)# vrrp 2 priority 95
switch1(config-if)# vrrp 2 track 1
switch1(config-if)# vrrp 2 track 2
switch1(config)# track 1 interface e1/0 line-protocol
switch1(config)# track 2 interface e0/0 line-protocol
switch2(config)# int vlan 2
switch2(config-if)# vrrp 1 ip 192.168.2.254

switch2(config-if)# vrrp 2 ip 192.168.3.254
switch2(config-if)# vrrp 2 preempt
switch2(config-if)# vrrp 2 priority 120
switch2(config-if)# vrrp 2 track 1
switch2(config-if)# vrrp 2 track 2
switch2(config)# track 1 interface e1/1 line-protocol
switch2(config)# track 2 interface e0/1 line-protocol
注：vrrp在IOU中测试，虚拟IP不通，需要使用是本地ios测试
