Link Packet Loss - Switch over to alternate link

Hello - I have a scenario. I have 2 Link on a Cisco Router. Primary Link A and Secondary Link B. I configured IP SLA Tracking (ICMP ECHO) such that when Primary Link A ISP IP address is not reachable, Track triggers Link B to be on the Routing table. This works very well so far

 

Problem: Whenever there is a ICMP Packet drop/loss, the Track flaps and network goes unstable between Primary Link A and Secondary Link B. so, we manually shut down Link A till the issue is restored

 

What is the solution to detect the Packet loss and keep the Link A shut/inactive till the Packet loss issue is solved and preempt?

 

Thanks in advance

Sairam

Possibly PfR. Otherwise, your own EEM script.
