Interface Tracking Loop

Capture.PNGHi All, I have a followinf scenario in my organization and i need help to resolve this. 
Tracking is enabled on mentioned link and both are showing each other UP.
Now if primary link of both isps get down (in our scenario traffic comes to the R2 then R2 due to tracking sends it to R1, At R1 both links are down then R1 due to tracking sends it to R2 and vice versa and loop is formed how to get rid of it?) Kindly share your views and further: 
1.ISPs to Routers ebgp 

2.R1 to R2 ibgp

I am sorry but I didn't understand why would you track the interface connecting iBGP neighbors. Based on the drawing you posted it appears R1 is the primary router for your network, so is there any policy configured when one of the primary WAN link fails on R1? Are you advertising prefixes to the ISP, if so are you using as-path prepend to choose link over another for inbound traffic?

 

It would be helpful if you can provide more details.

Thanks for your reply. It was something wrong in my question. I have got the solution. Basically ibgp was not configured and prefixes were statically routed and tracking was enabled in sla monitoring.
Thanks again for your precious time :)
