The document is ready for publication as a standards track RFC, however I have
a few comments.

Minor issues:

TRILL-PORT-VER sub-TLV should be "PORT-TRILL-VER" sub-TLV.(there are a few

Nits/editorial comments:

- Suggestion: [Page 6], line 2, spell out first occurrence LSP

- Clarification:[Page 6], Section 2.1, line 5, add a comma "," after "traffic
engineered frames"

- Typo:[Page 6], last word, "contain" --missing s--> "contains"

- Suggestion: [Page 7], Section 2.2, line 2, spell out first occurrence of
"Reverse Path Forwarding Check" and then use "RPFC" in the rest of the document.

- Clarification:[Page 10], Section, line 5, sentence starting with "RB2
MUST advertise ...": we could omit the second occurrence of "it might use" in
that sentence.

- Clarification:[Page 10], Section, 3rd line from last, "end stations
connected to RB": "a RB" or "RBs"?

- Typo: [Page 11], Section 3.1,"( j, k)" --remove extra space--> "(j, k)"

- Suggestion: [Page 11], Section 3.2, "already in flight" ----> "already in

- Typo [Page 12]:"many multi-destination frame"--missing s--> "many
multi-destination frames"

- Clarification:[Page 13], Point 4. , Sentence 2: suggested clarification:

"It does so by checking LSPs it receives and updating its link state database

is IS-IS reachable."

"Margin" below."

- Suggestion: [Page 19], spell out first occurrence of EISS

- Suggestion:[Page 21], Point 1, not clear what the new text becomes.
Suggestion: refer to last paragraph of section 3.1 instead of paragraph before
3.2, and propose the new sentence.

- Clarification:[Page 21], Point 2, it is not clear what the change is to
section 3.2 of RFC6327.

- Clarification:[Page 21], Point 3, it would be clearer to say "bullet A9 is
added" (if this is an event like the rest of the bullets in section 3.3 of

- Clarification:[Page 22], section 10.1,"disagreement over the Designated VLAN
or the like". Suggestion: replace the term "or the like" with other examples or
remove the term.

-Typo: [Page 22], section 10.1, "each others frames"---->"each other's frames"

-Typo: [Page 24], "DRB SHOULD NOT appointed"---->"DRB SHOULD NOT appoint", "an
VLAN"---->"a VLAN", "RBridged"---->"RBridge"

-Clarification:[Page 25], Section 11, Point 1, "The previously reserved",
reference to document.

- Clarification: [page 19/page 27], Informative References, reference [802], to
verify which standard we want to refer to for Canonical Format Indicator:

If it is "IEEE Std 802-2001: IEEE Standard for Local and Metropolitan Area
Networks: Overview and Architecture", then the date should be 7 February 2001."

However this specific document does not define CIF. You may want to refer to
