[c-nsp] Routing table

[Stephen J. Wilcox]

Christophe, 
 are you aware of a problem occurring? This is normal and common practice so I'm 
not sure why you want to change the behaviour... of course once you have 170000 
routes in the table you are forced to lookup from the whole set... the 
alternative being to filter routes inbound from the Internet to have a default 
and a subset of routes.
