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


- section 5: The tenant ID is sometimes described as "globally
unique" and sometimes (in 5.2) as "throughout the campus." The
latter seems likely correct to me. (As an aside, is this document
the first to introduce that concept to TRILL?)

- section 8: If IS-IS security is not actually used, (is that the
current deployment reality btw?) and if I can guess a tenant ID then
what new mischief can happen? If there is some, then perhaps you
ought recommend that tenant ID's be randomly selected within the
campus? (I see you use "1" in the example, which is pretty easy to
guess:-) I think one could argue that that (and maybe more) ought be
covered in section 8, if the current deployment reality is that no
crypto is actually used to protect most IS-IS traffic. Is it?
