  | The phrase "run the algorithm independently on each interface" may seem a 
  | simple thing to say, but when you have Ethernet and wireless, and 
  | (unknown to you) the wireless base station you're talking to is bridged 
  | onto the same Ethernet, the interfaces aren't independent any more, even 
  | if you wish they were.

All that is true, but this describes exactly the case where the "run the
algorithm independently on each interface" is required.   That is, on
the wireless, and on the ethernet, you pick a random address (different
random addresses 99.99% of the times) and probe that one.   Each interface
sees the other probe (because of the bridging) but they're for different
addresses, so ignored.

Maybe there's just a misunderstanding of what the text is attempting to
say there?

Or are you still believing that a host should pick one LL address, and
attempt to use the same one on every inteface?   We discarded that notion
ages ago, as I recall it.

  | Figure 1 "(Incorrect) Ambiguous Re-Use of Address 
  | Q" in draft-07 described the difficulty when another host has an IP 
  | address that's the same as one of your own IP addresses.

It attempted to describe a difficulty, but not one that ever made any
sense to me.
