Need help here. I did a ECMP load balance with 2 ISP and now I try to apply failover technique with this scenario: if the main ISP is down, the traffic moves to the backup ISP, and when the main ISP is up again, it goes back from the backup ISP to the main ISP. I found out that failover can be done with putting Distance parameter or with failover script. My question is: which one suites well with ECMP load balance?
I tried putting Distance parameter but it seems the route with Distance supersede the ECMP route so when I turn the main ISP back on, it results “Request Time Out” in ping test. I tried with script in this page https://wiki.mikrotik.com/wiki/ECMP_Failover_Script but it still result RTO.
I’m confused whether to use the Distance parameter or fix my script. Anybody please help.
