There might be a few duplicate packets seen in an A/A EVPN scenario when the remote PE device sends packets with IM label due to MAC not being learned on remote PE device but being learned on the A/A local PE device. The non-DF sends the IM-labeled encapsulated packet to the PE-CE interface after MAC lookups instead of dropping the packet, which causes duplicate packets on the CE side. PR1245316
