Summary:  Ready with nits

Major issues: NONE

Minor issues: NONE

Nits/editorial comments:

* In Section 4.5. "TRILL Over IP Transport IS-IS SubNetwork Point
of Attachment", the word "of" between ""

"""
The Hellos transmitted out [of] a port indicate what neighbor ports
that port can see on the link by listing what IS-IS refers to as the
neighbor port's SubNetwork Point of Attachment (SNPA)
"""

* In Section 5.2. "Encapsulation Agreement", the first sentence is
difficult to understand; I think it is missing the word "on" between
"sent out" and "a TRILL over IP":

"""
TRILL Hellos sent out [on] a TRILL over IP transport port indicate the
encapsulations for which that port is offering full support through a
mechanism initially specified in [RFC7178] and [RFC7176] that is
hereby extended.
"""

* In Section 5.4. "Native Encapsulation", the word "he" should be
"the" in the sentence "Where he UDP Header is as follows".

* In Section 5.6.1. "TCP Connection Establishment", the word
"connections" should be singular (or the leading "a" dropped) in the
fragment "try to establish a TCP connections to each of them".

* In Section 5.6.1. "TCP Connection Establishment", the occurrence of
"P!" should be changed to "P1".
