Re: [Roll] MOPex updates and extended control option query

[[e-mail]]

Hello Rahul,

I’m digging up open items regarding our active documents., sorry if this comes up very late.
I’m curious about your proposal for an option “for the node to not join the network at all (not even as 6LN) if a control option is not understood”.
Do you have a use case for it that you could share?
I fail to see in which circumstance the node should not be allowed to join as a leaf node?
Thanks

Dominique

Subject: [Roll] MOPex updates and extended control option query

Hello All,

The MOPex draft is refreshed with just editorial changes in this version.

However, I would like to raise one point that Pascal made during the IETF 110 session.

Currently, the MOPex draft extends the RPL control options with certain flags to handle cases where the control option is not understood by the node:
J-flag: Join only as 6LN
C-flag: copy option as-is even if not understood
I-flag: Ignore message altogether.

We could have an option for the node to not join the network at all (not even as 6LN) if a control option is not understood.
Any feedback on this would be appreciated.

Thanks,
Rahul

Abstract:
   RPL allows different mode of operations which allows nodes to have a
   consensus on the basic primitives that must be supported to join the
   network.  The MOP field in [RFC6550] is of 3 bits and is fast
   depleting.  This document extends the MOP for future use.




Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org<http://tools.ietf.org>.
