attached the scenario..
Where link 1 is primary link
link 2 is secondary
our requirement is once Link 1 fails , traffic should pass over link 2 and once link 1 gets back traffic should restore over link1
here condition is link 1 traffic is passing over eigrp routing protocol and link 2 traffic
can we reach the requirement over policy based interface tracking ,
if yes how to configure tracking using Dynamic routing protocol
