    DESCRIPTION
        "This document contains the Management information base for
        Bidirectional Forwarding Detection(BFD) Protocol as defined
        in draft-ietf-bfd-base-06.txt.

        BFD is a protocol intended to detect faults in the
        bidirectional path between two forwarding engines, including
        interfaces, data link(s), and to the extent possible the forwarding
        engines themselves, with potentially very low latency.  It operates
        independently of media, data protocols, and routing protocols.

        This MIB module is based on the Internet Draft
        draft-ietf-bfd-mib-03.txt and draft-ietf-bfd-mib-04.txt"
