 standby version 2
 standby 1 ipv6 autoconfig

!--- Assigns a standby group and standby IP address.


 standby 1 priority 120


!--- R1 is configured as the active router. !--- This is done by assigning a priority value !--- (in this case 120) to the router's Fa0/0 interface. !--- The default priority value is 100.


 standby 1 preempt delay minimum 30

 !--- The preempt command allows the router to become the !--- active router when it has the priority higher than !--- all the other HSRP-configured routers. !---- Without this command, even if a router has higher !--- priority value, it will not become an active router. !--- The delay minimum value causes the local router to postpone !--- taking over the active role for a minimum of 30 seconds. 

 standby 1 track Serial0/0 90

 !--- Indicates that HSRP tracks serial0/0. !--- The interface priority is configured (in this case 90) which !--- indicates that if the tracked interface goes down the router !--- priority value is to be decremented by 90. !--- Default decrement value is 10.
