#8: absent MAC address of default route?

 In environments where this is a significant amount of additional traffic,
 presumably ND will be the preferred mechanism for delivering the default
 route.

 I think this is an unnecessary optimization.   What's the use case where
 both ND is not preferred, and bandwidth is so constrained as to make this
 a problem?
