Document: draft-ietf-rtgwg-spf-uloop-pb-statement-08 Reviewer: Dan Romascanu Review Date: 2018-12-11 IETF LC End Date: 2018-12-18 IESG Telechat date: Not scheduled for a telechat Summary: Ready This document analyzes the impact of using non-standardized IGP Link State implementations resulting in non-consistent tuning of parameters in the network and increased possibility of creating micro-loops. It can be viewed as a problem statement for standardized solutions like RFC 8405. The document is short and clear for implementers and operators familiar with networks running this class of protocols. Diagrams and table help in reading and understanding the material. Major issues: none Minor issues: none Nits/editorial comments: 1. In the introduction: > For non standardized timers, implementations are free to implement it in any way. It is not obvious what 'it' means. I guess it's about different values of timers resulting in the possibility of micro-loops creation, but it would be better to clarify. 2. It would be useful to provide short explanations that make the figures more clear. In fig. 1 - what do the nodes represent (routers implementing the protocols), in fig. 2, and 3 - the abbreviations on the y axis
