I'll take a "guess" at your problem...

If you have everything "centralized" into one PE doing your intra-VRF 
iBGP, and also providing VRF-specific routing processes...

The intra-VRF routes are propagated locally via iBGP and the vrf 
route-target import/export specifications.

To redistributed "learned" routes from the VRF-specific routing 
processes into the iBGP mesh, you must 'redistribute [protocol]' in the 
BGP address-family ipv4 vrf specification.

To redistributed "learned" routes from the iBGP import/export process 
back into the VRF-specific routing processes, you must 'redistribute bgp 
[asn]' in the routing process vrf specification.
