Summary:  This well-written draft is an Experimental specification for how
encapsulation is performed in the BIER architecture in order to optimally
forward a packet through a multicast domain while not being burdensome to
intermediate routers.

This draft is ready with issues.

Major issues: None.

Minor issues: This Experimental draft specifies that entries to its BIER Next
Protocol Identifiers registry are to be done according to the "Standards
Action" policy of RFC 8126.  It's not entirely clear to me whether RFC 8126's
requirement that such entries be from Standards Track or BCP documents applies
to the initial set of values.  If it does, then there's an issue here between
RFC 8126 and this draft's desired status.

Nits/editorial comments:


Replace "ethernet" with "Ethernet" throughout.

Replace "ethertype" with "Ethertype" or "EtherType" throughout.  (IEEE usage is
varies between the two, unfortunately.)


Page 3, second bullet item: change "is" to "are".

Page 4, last paragraph: this paragraph is redundant to one it follows fairly
closely in Section 1.  Consider striking it, although it's not harmful.

Page 5, Section, 1st paragraph, 3rd sentence: change "ISIS" to "IS-IS".

Page 9, OAM definition, 1st paragraph, second sentence: delete a duplicated
"the" in the sentence.

Page 10, Section 2.1.3, 1st paragraph, 2nd sentence: delete a duplicated "in"
from the sentence.
