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

 

R1#sh ip ospf neighbor

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 ....
