Redistribution & Sham-link ISSUE

Hi All
I am facing an issue in the OSPF sham-link configuration , my setup is two
customer sites connecting to MPLS back bone at the same time have a
connection in between the sites.

Say I have two sites Site A and Site B.both sites have O , O IA , O E2
routes. when i am redistributing from the OSPF to Address family of
perticular VRF* ( redistribute ospf 1 vrf VPNX match internal external 1
external 2)* , it is working perfect.

But if i didnot include the *match internal external 1 external 2 *in the
PE(connecting to Site B) when redistributing , I cannot reach those
External routes from Site A,
but the Site A routers donot remove those Routes from the routing table.

Can anyone help to overcome this issue.

When i was troubleshooting this ,
Even i remove all the redistribution in the PE routers , all the routes are
learning through the sham-link , but readability is not there.

Regards,
Anbu.
