This isn't terribly tricky. Just setup the redistribution into BGP. The 
OSPF routes will be preferred but the BGP routes will be present, which 
you can verify. Then disable redist into OSPF. "Separation" just means 
"only have network statements for your p2p and loopback nets in OSPF".

If you do have to use OSPF, redist-ing from the CE OSPF process into BGP 
is superior to redist-ing from CE to PE OSPF, because it isolates the PE 
OSPF process completely from customer operation.
