COMMENT:
----------------------------------------------------------------------

I had the same question that Ben poses in his DISCUSS, and support untangling
the question before continuing progression of the document.

---------------------------------------------------------------------------

I've dug around some of the BFD documents but can't quite figure out how the
tail knows which address to use when responding to a multipoint poll query.
The reason I went looking is: if the head has some means of indicating to the
tails where such responses should be sent, then it has the ability to coordinate
a massive DDoS attack on a selected victim address. Is this possible?
