                        Babel Information Model
                 draft-ietf-babel-information-model-05

Abstract

   This Babel Information Model can be used to create data models under
   various data modeling regimes.  It allows a Babel implementation (via
   a management protocol or interface) to report on its current state
   and may allow some limited configuration of protocol constants.

1.  Introduction

   Babel is a loop-avoiding distance-vector routing protocol defined in
   [I-D.ietf-babel-rfc6126bis].  [I-D.ietf-babel-hmac] defines a
   security mechanism that allows Babel packets to be cryptographically
   authenticated, and [I-D.ietf-babel-dtls] defines a security mechanism
   that allows Babel packets to be encrypted.  This document describes
   an information model for Babel (including implementations using one
   of these security mechanisms) that can be used to create management
   protocol data models (such as a NETCONF [RFC6241] YANG [RFC7950] data
   model).

   Due to the simplicity of the Babel protocol, most of the information
   model is focused on reporting Babel protocol operational state, and
   very little of that is considered mandatory to implement (contingent
