The IESG has received a request from the Routing Area Working Group WG (rtgwg) to consider the following document: - 'Link State protocols SPF trigger and delay algorithm impact on IGP micro-loops' <draft-ietf-rtgwg-spf-uloop-pb-statement-08.txt> as Informational RFC The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2018-12-18. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract A micro-loop is a packet forwarding loop that may occur transiently among two or more routers in a hop-by-hop packet forwarding paradigm. In this document, we are trying to analyze the impact of using different Link State IGP (Interior Gateway Protocol) implementations in a single network, with respect to micro-loops. The analysis is focused on the SPF (Shortest Path First) delay algorithm. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-rtgwg-spf-uloop-pb-statement/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-rtgwg-spf-uloop-pb-statement/ballot/ No IPR declarations have been submitted directly on this I-D.
