[c-nsp] NPE-300 and BGP table size

[Mark Kent]

A bit late, but I do this:

   ip prefix-list twentythree permit 192.0.0.0/5 le 24
   ip prefix-list twentythree permit 200.0.0.0/6 le 24
   ip prefix-list twentythree permit 204.0.0.0/8 le 24
   ip prefix-list twentythree permit 0.0.0.0/0 le 23

and end up with about 120k paths from both neighbors.  
With 12.0(27)S4 and "soft-reconfiguration inbound", 
I have:
               Head     Total(b)     Used(b)     Free(b)   Lowest(b)  Largest(b)
