Hi Mosiur,

Do you see traffic on attachment circuit (GigabitEthernet0/0/3.3001) on both the peer routers? Check if the counters are incrementing

show ethernet service instance id 3001 interface GigabitEthernet0/0/3.3001 detail  << to match traffic at EFP level.

>> If the "Pkts In" counter is not increasing, that means some issue on the CE

show mpls l2transport vc 3001 detail   <<< try to match output of this cli on both routers.
