The IESG has received a request from the Open Shortest Path First IGP WG (ospf) to consider the following document: - 'OSPF Link Overload' <draft-ietf-ospf-link-overload-11.txt> as Proposed Standard 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 2018-01-16. 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 When a link is being prepared to be taken out of service, the traffic needs to be diverted from both ends of the link. Increasing the metric to the highest metric on one side of the link is not sufficient to divert the traffic flowing in the other direction. It is useful for routers in an OSPFv2 or OSPFv3 routing domain to be able to advertise a link as being in an overload state to indicate impending maintenance activity on the link. This information can be used by the network devices to re-route the traffic effectively. This document describes the protocol extensions to disseminate link- overload information in OSPFv2 and OSPFv3. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-ospf-link-overload/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-ospf-link-overload/ballot/ The following IPR Declarations may be related to this I-D: https://datatracker.ietf.org/ipr/2577/
