Summary: The draft is mostly ready for publication as an informational RFC, but
I have some editorial comments that might be worth considering prior to
publication.
Major issues:
None
Minor issues:
None
Nits/editorial comments:
-- Please expand the "P" in "P Router" in the first mention.
-- section 3.1, paragraph 2: "... and also at least some of their network core
facing interfaces along with some P routers in the IPv6 network."
This seems vague. Do you mean to say that each must have one or more of their
core facing interfaces in the topology? Can "some P routers" be stated more
precisely in terms of the requirements for a particular AFXLBR?
-- 3.1, paragraph 3, 2nd sentence:
The sentence is hard to parse. Comma usage seems off, and the antecedent of
"it" is unclear. I suggest breaking it into multiple simpler sentences.
-- 3.2: "... following sub-sections"
Explicit references would be helpful, if this text is ever quoted outside the
draft.
-- 3.4:
inconsistent hyphenation of "MTID" vs "MT-ID"
"In addition, the MT bit in the OSPFv3 Option field must be set."
Did you mean that to be an all-caps MUST? I'm neutral on whether it is
required, but you did use MUST for similar text in the previous section.
-- 4.1, last 2 paragraphs:
Is the 2119 language in these paragraphs new normative language, or
restatements of normative text in the referenced RFC? If the latter, it would
be better use descriptive rather than normative language here.
-- 5, 2nd paragraph : " ... the IPv4 networks and IPv6 networks belong to
separate and independent Autonomous Systems"
The draft has other assertions that appear to say that they are all assumed to
be in the same autonomous system. (E.g. Section 3.3)
-- 8:
Which is the backdoor? The direct ipv4 route, or the imbedded route? I can
infer the answer to that, but not until the last sentence.
-- 11, 4th paragraph:
What's the antecedent of "this engineering practice"? This draft? The use of
the the same SA?
-- 11, last paragraph:
Again, what is the antecedent of "this engineering practice"? Aren't the
security details of that what this section is about in general?
