given that you show three links, the two hosts NetBSD1 and NetBSD2
have two addresses, one on each link.

What is your routing setup? Is the prefix on the two links really
supposed to be the same? On which device do "Linux" and "NetBSd3"
have that non-linklocal address? How do the routing tables look
on each of the four mentioned machines?

Before you answer all that, I have no idea what you want to tell
us by "routing looks well". (In fact, if the "Prefix" to the left
and the right are the same, there can't be any routing that I 
would call "well".)
