Can you explain in what circumstance this would be normal?  IIRC, OSPF 
has an AD of 110 and iBGP 200, so even if the routes weren't known via 
connected, how would they randomly compete for space in the FIB?  I 
don't have OSPF or BGP running on any SVIs, so this is an honest 
question, not snarkiness, since I may find myself in this scenario in 
the not too distant future, albeit on 7600s rather than 6500s.  Pointers 
to docs would be great.
