[Ready with issues] This draft defines a means to carry additional per-node administrative tags with the IS-IS protocol. These tags can be used along with local policy to simplify the management of routing and path selection. This specification gives informative examples of such tag usage but does not otherwise prescribe the meaning of the tags. Major issues: None Minor issues: Page 5, section 4.2, 2nd paragraph, 1st sentence: The sentence states: "Being part of the Router CAPABILITY TLV, the node administrative tag sub-TLV MUST be reasonably small and stable." If you're going to make this a MUST, you've got to at least give a definition of "reasonably small" and perhaps even "stable" in the context of this specification. As it stands, there's no test for whether the MUST is enforceable or understandable between parties. Nits: General: The use of capitalization of Node administrative tag varies throughout the document. It seems clear that you mean for it to be written as "Node Administrative Tag" when referring to the name of sub-TLV. For other uses, I would suggest using "node administrative tag" (all lower case) consistently. Use that to replace "Node administrative tag". Specific: Page 3, 1st paragraph after the labeled items at the top, 3rd sentence: change the first "TLV" to "sub-TLV". Page 3, Section 2, 2nd paragraph: append a comma after "another". Page 3, Section 3, 1st paragraph, 1st sentence: change "a" before "IS-IS" to "an". Page 3, Section 3, 1st paragraph, 2nd sentence: change "Capablity" to "CAPABILITY". Page 3, Section 3, 1st paragraph, 3rd sentence: change "Operator" to "An operator". Change "diiferent" to "different". Page 3, Section 3, 2nd paragraph, 1st sentence: insert "the" before "Node". Page 3, Section 3, 2nd paragraph, 2nd sentence: change "topology specific" to "topology-specific". (That is to say, swap the space for a hyphen.) Page 4, Section 3.1, Value definition: insert "node" before "administrative". Page 4, Section 4.1, 1st sentence: change "Node" to "node". (See general nit.) Page 4, Section 4.1, 3rd sentence: delete the space after the slash and before regulations. Page 5, 3rd full paragraph, 4th sentence: delete the spaces after closing parenthesis and the terminating period. Page 6, Section 4.3, 1st paragraph, 2nd sentence: change "Node" to "node". (See general nit.) Change the first "TLVs" to "sub-TLVs". Page 6, Section 4.3, 2nd paragraph, 2nd sentence: delete the space before the comma. Page 6, Section 5, 1st paragraph, 1st sentence: change "Node" to "node". (See general nit.) Page 6, Section 5, 1st paragraph, 4th sentence: change "Following" to "The following". Page 6, Section 5, 1st paragraph, 5th sentence: change "section-3" to "section 3". Page 7, Section 6, 2nd paragraph, the comma should be rejoined with the closing parenthesis. Page 7, Section 7, 1st paragraph, 3rd sentence: change "is" to "are". Page 7, Section 8, 1st paragraph, 2nd sentence: delete "The" before "YANG". With the change in the rest of the sentence, "The" becomes superfluous. Page 8, Section 9: change "Capabality" to "CAPABILITY".
