Re: [6lowpan] "Advertize on Behalf" flag in ARO

(maybe not so surprising, )
I would like to support Mukul.

RPL is one routing protocol, but 6LoWPAN may run under any routing protocol - or none at all.

In all cases, a sleeping node can benefit from asking a neighbor router to provide connectivity to that node.
To me this definitely sounds like a feature that belongs to the 6LoWPAN ND toolbox.

Thanks,
  Anders

Hi Carsten

>Hosts don't take part in routing protocols

I agree absolutely.

>The only source of information about reachability and network configuration a host has is ND (and DHCP for some of the latter, if present).

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.

Thanks
Mukul

Hosts don't take part in routing protocols, so I don't understand this sequence.
The only source of information about reachability and network configuration a host has is ND (and DHCP for some of the latter, if present).
