switch1(config)# int vlan 2

switch1(config-if)# vrrp 1 ip 192.168.2.254

switch1(config-if)# vrrp 1 preempt

switch1(config-if)# vrrp 1 priority 120

switch1(config-if)# vrrp 1 track 1

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 1 preempt

switch2(config-if)# vrrp 1 priority 95

switch2(config-if)# vrrp 1 track 1

switch2(config-if)# vrrp 1 track 2

switch2(config)# int vlan 3

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中測試，虛擬IP不通，需要使用是本地ios測試
