Re: [Roll] I-D Action: draft-ietf-roll-mopex-01.txt

Hi Rahul

In section 4 its mentioned
"I" (Ignore) bit in Option Flags: A node which does not understand the
Option Type MUST ignore this whole message if the ’I’ bit is
set. If ’I’ bit is set* than* the value of ’J’ and ’C’ bits are irrelevant
and the *message MUST be ignored.*"

1-  I didn't get why the whole message needs to be ignored if an option is
not understood?  I think this bit MUST say if the option is optional or
mandatory. If it's mandatory then 'J' flag will control
     if the node can join as a leaf or an LR.
    Am I missing something here?

2- There is a typo error (Than)

Thanks
Rabi
