OSPF WG, New version of the ospf-link-overload draft is posted. Editorial comments received so far have been addressed in this version.
There was one comments to move the link-overload sub-TLV to LLS in hello messages. Many implementations delegate the Hello processing to linecards/different deamons Once adjacency is established. Hello messages are not sent to control plane post adjacency establishment. The link-overload information typically needs to be processed after adjacency establishment, it introduces unnecessary complexity in hello processing. We had a discussion among authors on this and feel advertising link-overload sub-TLV in the LSAs is the most appropriate mechanism.

This draft is a work item of the Open Shortest Path First IGP of the IETF. Title : OSPF Link Overload Authors : Shraddha Hegde Pushpasis Sarkar Hannes Gredler Mohan Nanduri Luay Jalil Filename : draft-ietf-ospf-link-overload-07.txt Pages : 14 Date : 2017-07-02 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 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.
