Hi, Yao.

Thank you for the prompt update.
I am okay with the current version of this draft.

Note:
There is a reference to RFC5307 in paragraph 1 of section 3.1.
Since this draft defines new BGP attributes, it might be more
appropriate to refer to RFC7752(BGP-LS) instead of RFC5307(IS-IS).
However, we can address this later since it's pretty minor.

Thanks
Nat
