[c-nsp] MPLS is not working

[Ahmed Mohamed]

Hello,

i used dynamips to perform a topology
 the topology is as follows:

CEA-1<======>PE1-AS1<======>P1<======>PE2-AS1<======>CE2-A

<----------FR-----------><----------ppp-------><------ppp--------><-------FR--------->

<-------static----------><------OSPF--------><-----OSPF-----><------static------>
                                <----------------------TDP------------------->
                                <------------------i
BGP--------------------->

i ping CE to PE good and vice verse on both ends
PE to PE pings good, also PE to P

ping CE to CE is not working , not even pinging PE to remote CE

the vrf table looks perfect, all routes are in it
i don't know what would be the cause of the problem,

below is the logs from my topology, thanks to advise:
