[c-nsp] Sup2s and counting routes

[Jon Lewis]

With the useful life of Sup2s as full-table BGP routers coming to an end 
sometime real soon, I've been looking at our 6509s trying to figure out 
just how much time we have, and I'm a bit confused.

#sh ip ro sum | inc Net|Tot
Route Source    Networks    Subnets     Overhead    Memory (bytes)
Total           129159      103219      14760368    40044640

Adding up the networks and subnets, I get 232378.

#sh mls cef summary | inc routes
Total routes:                230023
     IP unicast routes:       230023
     IPX routes:              0
     IP multicast routes:     0

According to CEF, I don't quite have 232378 routes.  Is one of these 
"totals" more correct than the other?  Why might they differ?
