ECMP With PBF

[DennyChanditya]

Hi,

I have ECMP with PBF configuration for dual ISP.

ECMP using weight 100 on ISP A and 200 ISP B.

PBF rule user A to isp A, user B to ISP B.

default routing to ISP using the same metric

we expect that user A will go to ISP A, but in reality user A is expected to ISP A, but we saw on the log several user sometimes is still go to ISP B, even the PBF is enabled. same condition happen on user B.

is there anyone know how to fix this? or this is the ECMP behaviour even with pbf enabled?

Thanks

Hi @DennyChanditya 

Do you have PBF configured for specific APP-IDs? Do you mind to share your PBF rule?

Hi,

All my PBF is using any services, not specify the apps. in our lab and other cust it was normal using the same configuration. but we found this anomaly on pbf config. even the metric on both isp is different/same we still had the same issue

Thanks
