>From a quick read of the draft, my only comment is this:

- In Section 4:

   o  Hop Limit.  Set to 0xFF, and decremented by one by each router in
      the path to the egress router.

What's the rationale of 0xFF (the possible maximum hop limit)?  It's
way too large compared to other general cases, and it's not
immediately clear how the L2TP usage is different.

As for volunteering to do a 6man review: if there's no other (or
enough) volunteer who is more familiar with the underlying topic, I'm
willing to spend my time for it.  But I'm afraid I'll not be able to
provide very useful feedback due to lack of my understanding of the
background technology (as it's suggested by the fact that my only
comment so far is the above one).  I'm stating this anyway as I've not
seen any public response to the request yet, but if there are already
volunteers who replied offlist, please just ignore this paragraph.
