In MPLS network with VRFs, there are two labels on the packet, one is the MP-BGP label and the other is LDP label. Does the MP-BGP label have EXP bit? Or it's only on the LDP label?

Thank you
Hi,
sure, it does have EXP bit. Actually both labels have EXP bit.
Yes. Both the labels are 4byte long and have the EXP bits also. When outer most label is removed the EXP is copied from outer label to inner label.
