R1---R2---R3---R4---R5

OSPF as IGP

Bi-directinaol tunnels between R1 --- R5

Bi-directional Forwarding Adjacencies is configured in tunnels

Here u can see === I have only one neighbor .... forming

R1#sh ip ospf neighbor

Neighbor ID Pri State Dead Time Address Interface

5.5.23.2 1 FULL/DR 00:00:37 5.5.12.2
 FastEthernet1/0

R5#sh ip ospf neighbor

Neighbor ID Pri State Dead Time Address Interface

5.5.45.4 1 FULL/DR 00:00:38 5.5.45.4
 FastEthernet1/0

R1#show ip cef 5.5.5.5 de

5.5.5.5/32, epoch 0

  local label info: global/16

  nexthop 5.5.12.2 FastEthernet1/0 label 17

R1#

R5#sh ip cef 5.5.1.1 de

5.5.1.1/32, epoch 0

  local label info: global/16

  nexthop 5.5.45.4 FastEthernet1/0 label 16

R5#sh mpls for 5.5.1.1

Local Outgoing Prefix Bytes Label Outgoing Next Hop

Label Label or VC or Tunnel Id Switched interface

16 16 5.5.1.1/32 0 Fa1/0 5.5.45.4

R5#

R1#sh mpls for 5.5.5.5

Local Outgoing Prefix Bytes Label Outgoing Next Hop

Label Label or VC or Tunnel Id Switched interface

16 17 5.5.5.5/32 0 Fa1/0 5.5.12.2

R1#

R5#sh mpls tr forwarding-adjacency

  destination 5.5.1.1 has 1 tunnels

    Tunnel15 (load balancing metric 0, nexthop 5.5.1.1)

                (flags: Forward-Adjacency, holdtime 1500)

R1#sh mpls tr forwarding-adjacency

  destination 5.5.5.5 has 1 tunnels

    Tunnel15 (load balancing metric 0, nexthop 5.5.5.5)

                (flags: Forward-Adjacency, holdtime 1500)

Can any help help me to solve this ....

What i am Missing

i can form Neighbor relationship ..........
