That's what has always confused me.  Part of the reason we may not is 
that the rogue comes on-line at a time when nobody is doing DHCPDISCOVER 
and then goes off-line.  OTOH, if the rogue sends out just one RA, other 
machines will configure the address and might even add a candidate route 
immediately, regardless of whether they already have a v6 address.

However, I have been in other situations where I see RAs in IPv6, but I 
don't have rogue DHCP issues in v4 on a particular net.  (At the same 
time, we do see a bunch of rogue DHCP servers on our wireless nets at 
Berkeley.)
