Just a guess: do you have vrf-table-label configured? If you have, at
egress PE the packet is logically received by LSI interface, so you
should apply your EXP classifier to those interfaces, too. This can be
accomplished by adding something like "set class-of-service
routing-instances <vrf> classifiers exp BA-exp".
