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 value on one side of the link is not sufficient
to divert the traffic flowing in the other direction.
It is useful for the routers in an OSPFv2 or OSPFv3 routing domain to
be able to advertise a link as being in a graceful-shutdown state to
indicate impending maintenance activity on the link. This
information can be used by the network devices to reroute the traffic
effectively.
This document describes the protocol extensions to disseminate
graceful-link-shutdown information in OSPFv2 and OSPFv3.
This document is a product of the Open Shortest Path First IGP Working Group of the IETF.
This is now a Proposed Standard.
