Hello,
on the hub, it looks like you are missing the lines in bold:
interface Tunnel1
ip address 172.16.0.8 255.255.255.0
no ip redirects
ip mtu 1476
ip nhrp authentication DMVPN
--> ip nhrp map multicast dynamic
ip nhrp network-id 1
ip nhrp holdtime 100
ip nhrp nhs 172.16.0.8
--> no ip split-horizon eigrp 1
ip nhrp redirect
ip tcp adjust-mss 1436
tunnel source 192.168.10.2
tunnel mode gre multipoint

hi again

thank you for your helps

i found the solution
first check the mpls config and be sure that #sh mpls ldp nei is right
then check the ospf config and the redistribute of bgp and ospf in all the router
then check in the PE #sh ip bgp all sum or #sh ip bgp all is correct and the state is up.
this is what i did and now it's working.
