Getting summarized routes plus individual routes at the same time in the routing table.

Summarization is performed on R4, which can be verified by the Null0 entry. But routes are not getting summarized on R6. Need help in rectifying the issue. Please find the topology below.

Hi  Aaradhana 

Can you please send the database table of R2 and R3 . It can help more to understand that  what will be the problem .  Because , i have looked that on R2 you has configured virtual-link . which can be the cause of problem .
