OSPF is a link-state intra-domain routing protocol used in IP
networks. Routers find new and detect unreachable neighbors via Hello
subprotocol. Hello OSPF packets are also used to ensure two-way
connectivity within time. When a router restarts its OSPF software,
it may not know its neighbors. If such a router sends a hello packet
on an interface, its neighbors are going to reset the adjacency,
which may not be desirable in certain conditions.  This memo
describes a vendor specific mechanism that allows OSPF routers to
inform their neighbors about the restart process.  Note that this
mechanism requires support from neighboring routers.

NOTE:   The mail server at ietf.org can return the document in
        MIME-encoded form by using the "mpack" utility.  To use this
        feature, insert the command "ENCODING mime" before the "FILE"
        command.  To decode the response(s), you will need "munpack" or
        a MIME-compliant mail reader.  Different MIME-compliant mail readers
        exhibit different behavior, especially when dealing with
        "multipart" MIME messages (i.e. documents which have been split
        up into multiple messages), so check your local documentation on
        how to manipulate these messages.
