cisco_track_hsrp_standby
我的模拟器版本不支持VRRP的track，只能使用HSRP了。。。应该说，track也就是这么用的。。。!
!
track 2 ip route 23.1.1.3 255.255.255.0 reachability

interface FastEthernet0/0
ip address 123.1.1.3 255.255.255.0
duplex full
standby 2 ip 123.1.1.1
standby 2 priority 110
standby 2 preempt
standby 2 track 2 decrement 20

============================================
实验证明track是相当有用的。
