Hi Khan
You need eBGP multihop/ttl2 if the neighbour address is not on a 
directly connected subnet i.e. is two hops away.  This has nothing to 
do with next-hop-self or black holing traffic.

Could you tell me where you have seen the this I can explain better.  
I'm assuming its in our documentation somewhere.
