The issue was resolved by some config change at Ericsson router.
We had tested the working config in lab between Juniper devices & shared the working config with customer.
Even with config changes at ACX7k, it was not working & they later corrected the config at Ericsson, which cleared the issue.
Below are the working config & output from ACX7K lab.
