Edmar,  
Can you provide us with the policy configuration from the Junipers? 
vrf-import Huawei_Iu_U_import;
vrf-export Huawei_Iu_U_export;
Those two specifically.

 a "show ip bgp v v Huawei_Iu-U x.x.x.x" From the Cisco routers where
x.x.x.x is the source IP of where the traffic is coming from to the
Cisco destinations? , a "sh mpls forwarding-table 10.44.105.3" and ""sh
mpls forwarding-table 10.44.105.4"  When the problem is happening of
course.
