ECMP link monitor 7.1.4

We had an issue with our secondary ISP last night that ECMP didn't handle passing all traffic to the promary ISP as the interface was still up.Does anyone have a suggestion on how to monitor the ISPs and down the link that is having issues? Current configuration is using 1 vRouter on a PA500.

Hi,

You could try configuring BFD.

hope this helps,

If BFD is not an option, you can also set up Policy Based Forwarding with a monitor set to disable forwarding when an upstream device becomes unresponsive

Policy Based Forwared will never work with ECMP as I tried that couple time.

I beleve we need feature that ECMP can monitor next IP or next next IP that will solve our problem.
