section 6.7.1:

change:
   When processing a RPL message containing an option for which the
   Option Type value is not recognized by the receiver, the receiver
   MUST silently ignore the unrecognized option and continue to process
   the following option, correctly handling any remaining options in the
   message.

To:
   When processing a RPL message containing an option for which the
   Option Type value is not recognized by the receiver, the receiver
   MUST silently skip the unrecognized option.  Unrecognized options
   in DIO messages SHOULD be copied into any subsequent DIO message
   transmitted.  On a per-DODAG basis,  unrecognized messages should
   reset the trickle timers if they are byte different than previous
   messages, thus causing a DIO to be immediately emitted.
