OK, so now I can send this "Advertize on Behalf" flag. As mentioned yesterday, there is a distinction between Frequently Listening (a.k.a duty cycled nodes) and what I call call-back nodes, i.e. nodes that depend on a router holding a mailbox for that node. Whether that mailbox feature is provided by any router, a few specialiezed routers or the border router is a network implementation decision. But how is that information conveyed to the sleeping node? In the RA? By asking the default router with some new message? Whereever this mailbox feature is offered in the network, this is where I will be sending my "Advertize on Behalf" flag if I am a call-back node. Forgive me if this is obvious. I think I am getting close to a "detail overload" ;-) Thanks, Anders

I agree. That's why I think 6lowpan ND should provide a mechanism to clearly identify a registered neighbor as a 6lowpan host or a 6lowpan router.
