  Bidirectional Forwarding Detection (BFD) Management Information Base

Abstract

   This document defines a portion of the Management Information Base
   (MIB) for use with network management protocols in the Internet
   community.  In particular, it describes managed objects for modeling
   the Bidirectional Forwarding Detection (BFD) protocol.

1.  Introduction

   This memo defines a portion of the MIB for use with network
   management protocols in the Internet community.  In particular, it
   describes managed objects to configure and/or monitor Bidirectional
   Forwarding Detection for [RFC5880], [RFC5881], [RFC5883], and
   [RFC7130], BFD versions 0 and/or 1, on devices supporting this
   feature.

   This memo does not define a compliance requirement for a system that
   only implements BFD version 0.  This is a reflection of a considered
   and deliberate decision by the BFD WG because the BFD version 0
   protocol is primarily of historical interest by comparison to the
   widespread deployment of the BFD version 1 protocol.

2.  The Internet-Standard Management Framework

   For a detailed overview of the documents that describe the current
   Internet-Standard Management Framework, please refer to section 7 of
   RFC 3410 [RFC3410].

   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB.  MIB objects are generally
   accessed through the Simple Network Management Protocol (SNMP).
   Objects in the MIB are defined using the mechanisms defined in the
   Structure of Management Information (SMI).  This memo specifies a MIB
   module that is compliant to the SMIv2, which is described in STD 58,
