HI frnds

I am not at all able to point out whats happening wrong . Dont want to
unconfigure and configure again untill I dig whats happening : PLzz help em

======s0/0/0=R4
                        | s0/0/1
                        |
                        |
                        | s0/0/1
======s0/0/0=R5

R4 and R5 are on PPP link but I had unsed IP unnumbered .
R4 getting IP from s0/0/0 ; R5 getting from virtual-template
R4 s0/0/0 is PPPoFR ..... R5 s0/0/0 is normal FR
