[mpls-linux-general] LSP hierarchy

[<bla...@in...>]

consider bellow :

       MPLS backbone
         -------
A-----B |       | C-----D
       \|       |/ \
        |J-----K|   E
        |       |
         -------> j->k
--------------------------> a->d/a->e

i just want to know about mpls tunnel hierarcy. if ilustration above like
this:
C->D : 18
C->E : 19
j->K : 35
if i use multiple push on backbone edge at j.
can this done by mpls tunnel?? i still confuse about mpls hierarchy
