ECMP Preferred Route

Hi All,


Does anyone have the answer as to how the Palo Alto choses the "preferred route" when ECMP is configured?





As per the runtime stats, the referred route for all these routes is (* flag) Both routes in each of the three destinations have been forwarded to the FIB as per the "e" flag.

I think that it depends of the load-balancing algorithm that you choose for ECMP routing.

If you use IP-Modulo (default option) you will always have same route as preferred route for a given source / destination couple.
