Hi Simon
(adding Tengfei as he can help also on this)
6LORH uses paging dispatch (rfc8025). This is a modification of the
dispatch byte so 4 of the last bits are used to indicate a page.
0 1 2 3 4 5 6 7
+-+-+-+-+-+-+-+-+
|1|1|1|1|Page Nb|
+-+-+-+-+-+-+-+-+
The possible values for the dispatch byte are then
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

in contiki you are using page 0.
We are pushing to have it implemented and some of the messages will be sent
using page 1. (we are discussing this now)
The question is what happens in Contiki if you receive a Dispatch byte with
a page that is not 0, e.g 110001 what Contiki will do? How hard would be
to add this Page 1 parsing assuming that what will follow will be IP
extension headers (6LoRH) with another dispatch starting with 10xxxxxx
