Document: draft-ietf-ospf-ttz-05 Reviewer: Orit Levin Review Date: 2017-01-03 IETF LC End Date: 2017-01-03 IESG Telechat date: (if known) Summary: This draft is well-written and well organized. It is basically ready for publication, but has a couple of nits that should be fixed before publication. Section 5.1 Paragraph 2 sets requirements for uniqueness of TTZ ID and of TTZ instance. The scope of the ID and the algorithm for ensuring its uniqueness needs to be specified. Also, the text about "TTZ instances" is somewhat confusing. Consider replacing it with "A TTZ MUST NOT have more than one instance in a network." Section 5.2 Paragraph 2 contains a typo. Replace "need configure" to "need to configure". Section 14 first table needs clarification. Consider replacing "9 Suggested" to "Value '9' is suggested" and stating the reason for not choosing the next available value. Thanks, Orit.
