Review result: Ready with Nits


I have reviewed this document as part of the Operational directorate’s ongoing effort to review all IETF documents being processed by the IESG.  These comments were written with the intent of improving the operational aspects of the IETF drafts. Comments that are not addressed in last call may be included in AD reviews during the IESG review.  Document editors and WG chairs should treat these comments just like any other last call comments.


Document reviewed:  draft-ietf-rtgwg-yang-vrrp-07



This document describes a data model for Virtual Router Redundancy Protocol(VRRP). Both version 2 and version 3 of VRRP are covered.


I have reviewed this document, it make sense and is written very clear.The YANG data model complies with NMDA architecture, and running with no error.


But I am concerning about some names of containers and leaves. For examples:


#1 the leaf virtual-routers, it seems to present the “number of virtual routers”, but the “virtual-routers” seems not able to help reader to immediate understand that this is a statistic parameter. I suggest changing it to “num-virtual-routers”.


#2 the leaf interfaces under the “vrrp-global-state-attributes” grouping, similar to #1;


#3 the container “statistics” under “vrrp-global-state-attributes” grouping. This container present the global statistics parameters. I suggest changing the name to “global-statistics”, since the same name also appear in “vrrp-instance” list.


#4 the operational state container “vrrp”, suggest modifying it to another name like “vrrp-state”, because it can help reader to quick understand what it means.


I know that these nits are not big deal, but I believe a clear nomenclature can help the reader understand what it really mean, especially for the reader who like to review the schema tree first. 


And also, a run of idnits revealed there were 8 warnings and 5 comments, please fix them.

Summary: 0 errors (**), 0 flaws (~~), 8 warnings (==), 5 comments (--).
