Hey biraj,
You are more than welcome, I don't believe that this would not be the case as Juniper is moving away from these types of platforms since they are considered legacy devices hence our chances of getting new features and enhancements are slim to none.
If this solves your problem, please mark this post as "Accepted Solution" so we can help others too \:)/
