HSRP - Tracking Using IP SLA

When link between R2 and R1 link goes down.Then Router R2 which is Active for VLAN2 has to be standby but this will not happen so we have to track this line by creating IP SLA or Tracking object which will decrement the priority value regarding respective HSRP. 

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------Configuration to create Ip Sla

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Check it by shunting down link FastEthernet0/1 on R2.

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------Now No Shut the link Standby router R2 become Active goes back to configured configurations
