The requirement for router("r" in below ase) between 2
targeted session peer is capable of mpls forwarding. 

Question: in the case where R2 as the egress for FEC x
and R2 assigns label 0 as label binding for fec x on
its session with R1 ;  now  If transit LSR 'r'
forward the mpls frame(w/ label 0) to R1, does it
violate the RFC since RFC says LSR has to pop mpls
frame w/ label 0 ?

   Yes, R2 will send out label mappings to R1,
provided the method of label
   distribution is downstream unsolicited. (This is
regardless of whether R1
   initially sends R2 the label mappings for the
corresponding FECs)
