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


- last para of section 5 (before 5.1) could do
with a bit of a re-write, it's not very clear.

- section 7: When this mechanism is used, can an
attacker who can delete or re-order packets
(which is v. similar to one who can replay
packets) cause any new bad outcomes due to the
verification of the out-of-order arrival? (Sorry,
I don't know IS-IS enough to know the answer
there, it's probably obvious.) If so, then maybe
that argues that one ought note that this doesn't
address such threats (but that this is still I
guess worthwhile).
