What do you use for signaling?  It seems like overkill to keep one
kind of traffic from using the MPLS operations if there are already
LSP's between the source and the destination and L3/L2vpn traffic
flowing between them.  You also give up some of the MPLS knobs such as
FRR and link/node protection. What do you gain by doing this?
