PBF not working when ECMP is configured

Venkatesan_radhakrishnan — Wed, 10 Oct 2018 12:26:30 GMT

I have two internet links and configured ECMP to do load balacing based on weight,

Here I want to allow few users from my internal to specific desired destination based on my PBF to take my ISP2 path.

But it is sometimes taking ISP 1 and sometimes ISP2 when I'm going through my ISP2 i can able to reach my destination server but fails when I'm going through ISP1.

ISP 1 is my primary link but I still want some destined traffic to go through ISP2 as because traffic going from my ISP2 will only be auto authenticated by webserver for logging in the user.

Is there any way to override ECMP or any other way to acheive this?

@Venkatesan_radhakrishnan,

Can you post a screenshot of what your PBF actually looks like. If I would have to guess you have specified an application and the reason you're seeing traffic on ISP1 is due to the Palo Alto not being able to identify the application right away.
