If you've not read the discussion last week, please check the
following links:

In summary, I believe I stand at the same position as yours.  My
understanding of the current wording in the 03 draft is that it
strangely talks about a "multihome version of on-link assumption".
While I was not convinced with Hesham's response that "this is
actually not the on-link assumption since this is just 'attempt', not
a 'requirement'", I suggested the above text in case we really still
want to emphasize the complexity specific to the multihomed case.  As
I stated in msg05058.html, my primary preference is to remove this
part altogether with the removal of the on-link assumption.
