Hello ! 
CISCO "MPLS VPN Architecture"  book 10th chapter Fig 10.8 says if you use
two different RDs for VRF's located at two PEs of same VPN
 BPG table contains two paths one with a rd of received one(from PE2) and
another with rd of local vrf at PE1 for same route. i.e two enties
 in bgp vpnv4 table. 
 Question here is why we need to have one more route with local rd prepended
in BGP table which is  received from another PE

Thanks
Veer
