Hello, 

A small comment on the draft draft-ietf-manet-bcast-02.txt.

I suggest the Unique Identifier MUST be placed in the Hop-by-Hop option header
instead of Destination option header.  Handling of the Destination option header
always take place after the handling of an eventual Hop-by-Hop option header. As
a result, nodes will process the Hop-by-Hop option header of a duplicated packet
before detecting it is a duplicated packet and dropping it. I'm quite sure this
is something we don't want to happen. 

Regards,
Guillaume Chelius.
