#173: Example of Flow from RPL-aware-leaf to non-RPL-aware-leaf


Comment (by mariainesrobles@gmail.com):

 Pascal said: “Yes

 We have to define the support for the non RPL leaf. This needs a different
 draft.

 My expectation is that the draft would indicate that the non RPL leaf is
 known by the 6LR through 6LowPAN ND with 6BBr extension (for the sequence
 number).

 IMHO, whether in storing or not storing, it would be good that the 6LR
 injects a DAO with self as transit with the external (E) bit set and the
 leaf address as target. So the other nodes know. So that in non-storing
 the root terminated the RH3 at the last router.

 Routing will take the packet back to that 6LR. The 6LR should strip the
 6LoRH, which is easy in the compressed format.

 But stripping is illegal unless there’s an IP in IP. So the problem is
 really the IP conformance. One way to solve that is to say that there is
 an implicit IP in IP from link local to link local in front of any 6LoRH.”
