    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
    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.
    STANDARDS TRACK: This document specifies an Internet Standards Track
    protocol for the Internet community, and requests discussion and suggestions
    for improvements.  Please refer to the current edition of the Official
    Internet Protocol Standards ( for the 
    standardization state and status of this protocol.  Distribution of this 
    memo is unlimited.
