 standby version 2
 standby 10 ipv6 autoconfig

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

 standby 10 preempt delay minimum 45

!--- 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 45 seconds.

 standby 10 track 1 decrement 10

!--- Configures HSRP to track an object and change the Hot Standby !--- priority on the basis of the state of the object. 


!--- In this example,the HSRP tracks the interface s1/0 mentioned !--- in the track process 1.


!--- Decrement value specified the amount by which the Hot Standby !--- priority for the router is decremented (or incremented) when the tracked object !--- goes down (or comes back up). The range is from 1 to 255. The default is 10.
