Last updates from TAC regarding the issue, as well as cluster flapping due to routed-pnote:
After reviewing the provided files, I can see the following:
From sk100500 limitation, PBR is not supported with:
- URL Filtering
- Anti-Spam blade
So the PRB is not supported in the environment, this can cause such behavior.
And after insisting on support:
Thank you for the update.
I understand what you are throwing to, however, those are the limitations.
It might be there is no correlation between the issue and the limitation, however, to investigate the issue we need to run a supported version.
Do you have any ideas how to proceed?
