Ralph, there is nothing wrong with doing that. Just make sure that you
don't have  any routers  without full tables  in your transit  path --
i.e. between  your  two  peering routers  -- and it   will be  fine as
long as  you don't  do anything wacky  like redistributing  BGP routes
into   OSPF. Be  careful with  redistributing in  the  other direction
also.

There's no  problem. It won't ruin  anything. It is  a pretty standard
setup.
