Deepak, Samer, and Tissa:



I reviewed draft-ietf-trill-oam-mib-07.txt  document as the routing directorate
review prior to the IESG evaluation.   Below is a summary of my review and the
text of the review.  Just in case you want a pdf of the review, I’ve attached

Routing Directorate Review

Reviewer:  Susan Hares

Version: draft-ietf-trill-oam-mib-07.txt

Hat: routing directorate

Other hats: TRILL WG chair

Status:  Technically ready to go.  Editorial suggestions are given to improve
readability.

Date:  8/19/2015

 ============

Caveat:  Routing Reviews are a part of the IETF LC process.  The authors





The reviewer reviewed the concepts in the following table, and found the
management concepts to be correct.  A Majority of this review is the editorial
issues:



Editorial issues arise from the text text in sections 5.3.2.1 – 5.3.2.4 and the
MIB text itself from various descriptions in the MIB.  As the MIB compiles, it
is important to re-compile this MIB after making editorial suggestions.



 In addition, the review found editorial issues (as indicated by other IESG
 members in review).  This reviewer provides alternative text for many of the
 issues.

Editorial Comments

1)



New format needs to be used (See Alissa Cooper’s comment)

2)



Section 5.3.2.1 – has indentation that needs to be move outward.

3)



Section 5.3.2.2 – editorial suggestions:

              Old: /The table uses four indices/

                New: /This table uses four indices/

4)



Section 5.3.2.3

Old : / Each row in the table represents a Path Trace Reply entry for the

           Defined MEP and Transaction./

New: /Each row in this table represents a Path Trace reply Entry for the

          Defined MEP and Transaction./



 Old: The first three indices identify the MEP and the fourth index specifies
 the transaction Identifier, and this transaction identifier/



New: The first three indices identify the MEP and the fourth index specifies
the transaction identifier.  This transaction identifier/



5)



Section 5.3.2.4

   Old:   This table includes Multi-destination Reply managed objects.

New:  This table includes managed objects for the Multi-Destination Reply.

Old: This table uses five indices: The first three indices are the indices of
the Maintenance Domain, MaNet, and MEP tables. The fourth index is the specific
Transaction Identifiet on the selected MEP. The fifth index is the receive
order of Multi- destination replies.

New:  This table uses the following five indices: 1) Maintenance Domain, 2)
MANET, 3) MEP tables, 4) Transaction identifier of selected MEP, and 5) receive
order of Multi-destination replies.
