I have seen this oddity too. All other systems configuring addresses,
and the safer ones until the limited (e.g. 255 for Solaris) but Linux
not setting a single one when flooding.

that being said, I recommend flood_router26 (new in 2.0) instead of
flood_router6. Its way more effective and also affects *BSD with a new
attack vector.
