Everything appeared fine however they had an issue reported with few of the MPLS VPNs.
From the graphs, they can see complete traffic loss since the RE switchover.
To resolve - deactivated the instance and reactivated, then was immediately able to ping.

MBB ASSISTD attribute was enabled on single node platforms and the app is not launched for master RE on chassis platform causing object anomaly resulting in forwarding issues.
The forwarding issues can be caused to any of the service/protocol running in the device (Eg: MPLS VPNs).
evo-pfemand and rpdagent object anomalies are being observed on ACX7509 resulting in forwarding issues. This day-1 issue.
This issue is fixed via below PR.

Workaround:
> Restart app mbb-assistd on both REs OR Router reboot
> The app restart may not help in all cases & we will have to deactivate/activate the service manually or go for router reboot
