Problem L3 mpls vpn cisco

I configure a mpls using "ospf +bgp"and "eigrp between CE<-->PE,at the moment I just have two clientes connect client one with "172.70.70.0/26",client two with"172.70.70.64/26" .

The routing looks fine from one client I can see the other clients network.But I cant ping from one client to another, but for example client1 has a 172.70.70.0/26 and I can see this routing in the client2 table...

Gateway of last resort is not set

172.70.0.0/26 is subnetted, 2 subnets

D 172.70.70.0 [90/33280] via 10.100.37.6, 00:09:30, FastEthernet0/0

C 172.70.70.64 is directly connected, FastEthernet1/1

10.0.0.0/30 is subnetted, 2 subnets

D 10.100.37.0 [90/30720] via 10.100.37.6, 00:09:30, FastEthernet0/0

C 10.100.37.4 is directly connected, FastEthernet0/0

do you have any idea whats went wrong ?

and I also can see both network from client 1 and two in both PE:

PE7#show ip bgp vpnv4 all

Route Distinguisher: 120:120 (default for vrf CLIENT2-1)

*>i10.100.37.0/30 172.25.3.30 100 0 ?

*> 10.100.37.4/30 0.0.0.00 32768 ?

*>i172.70.70.0/26 172.25.3.330720 100 0 ?

*> 172.70.70.64/26 10.100.37.530720 32768 ?

and from the PE I can ping just the connected CE not the other one CE.

Ping from the PE7 conneted to the client2 "172.70.70.64/26".
