[c-nsp] Verifying BGP Propragation

[Stephen J. Wilcox]

so this is expected behaviour

the key point here is that to provide transit you need to maintain as good paths 
as your competition which may include v large ISPs, in particular minimising how 
much of your transit customer traffic goes to your transit suppliers will help

at this point you drop into a peering vs transit debate and a whole bunch of 
associated economics which states even if you can buy transit for $10/mb you 
have to spend $30/mb to maintain a network if you want to stay in the game
