Arie, Indeed we have many VLANs and each VLAN should be marked with different EXP bits. I only copy a specific VLAN. The idea is don't trust in the source and remark with specific EXP bits to the upstream, the PE-P is mpls enabled. Anyway it's correct I have transit traffic originated by other devices connected to the 7600.
