Qing Li e034e82c56 The current routing code allows insertion of indirect routes that have 
gateways which are unreachable except through the default router. For
example, assuming there is a default route configured, and inserting
a route

	"route add 64.102.54.0/24 60.80.1.1"

is currently allowed even when 60.80.1.1 is only reachable through
the default route. However, an error is thrown when this route is
utilized, say,

	"ping 64.102.54.1"  will return an error

This type of route insertion should be disallowed becasue:

1) Let's say that somehow our code allowed this packet to flow to
   the default router, and the default router knows the next hop is
   60.80.1.1, then the question is why bother inserting this route in
   the 1st place, just simply use the default route.

2) Since we're not talking about source routing here, the default
   router could very well choose a different path than using 60.80.1.1
   for the next hop, again it defeats the purpose of adding this route.
