Thanks Ines. The updated text is more clear and in sync with other text in =
the section. Please find my resp inline.

Best,
Rahul

[IR] Thank you, we could delete the para if people/other coauthors agree. B=
ut in case that we want to specify the case on rebooting, would it the foll=
owing make sense?

"In the case of rebooting, the node (6LN or 6LR) does not remember the
RPI Option Type (i.e., whether or not the flag is set), so the node will no=
t trigger DIO
messages until a DIO message is received indicating the RPI
value to be used. The node will use the value 0x23 if the network supports =
this feature."

[RJ] Yes this para is more clear for me. Thanks.

Regarding the terminology: The draft terms, the new option type as "RPI Opt=
ion Type" (value 0x23) and the old "RPL Option Type" (value 0x63). Is this =
correct?

[IR] we define RPI here as follows:


RPL Packet Information (RPI): The abstract information that [RFC6550<https:=
//tools.ietf.org/html/rfc6550>]
   places in IP packets.  The term is commonly used, including in this
   document, to refer to the RPL Option [RFC6553<https://tools.ietf.org/htm=
l/rfc6553>] that transports that

   abstract information in an IPv6 Hob-by-Hop Header

Yes, with RPI Option Type we refer to the RPL Option described in 6553

[RJ] Great! Please also check the PR I raised on GitHub and use the changes=
 if it makes sense.
