Abstract

   This Babel Information Model provides structured data elements for a
   Babel implementation reporting its current state and may allow
   limited configuration of some such data elements.  This information
   model can be used as a basis for creating data models under various
   data modeling regimes.

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
   or both 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 for an
   implementation claiming compliance with this information model.  Some
   parameters may be configurable.  However, it is up to the Babel
