Hi Vignesh,
If you have learnt the same route through some other source with better administrative distance, the lowest will be installed in the routing table. For EX: if you receive a BGP update from neighbor for a route which is directly connected in ur router, the lowest AD (connected) will be installed in routing table and the one in BGP table will be marked as RIB failure.
Check your routing table and see if you have a route with lowest AD.
Regards,
Nagendra
