VRRP (Virtual Router Redundancy Protocol)

Hi Taslim,

For sure, it could be something as simple as this:

R1(config)#track 1 interface FastEthernet 0/0 line-protocol
R1(config)#interface FastEthernet 0/0
R1(config-if)#vrrp 1 track 1 decrement 50

or you can configure IP SLA and combine it with tracking like I did here:
