             Homenet profile of the Babel routing protocol
                  draft-ietf-homenet-babel-profile-07

Abstract

   This document defines the exact subset of the Babel routing protocol
   and its extensions that is required by an implementation of the
   Homenet protocol suite, as well as the interactions between the Home
   Networking Control Protocol (HNCP) and Babel.

1.  Introduction

   The core of the Homenet protocol suite consists of the Home
   Networking Control Protocol (HNCP) [RFC7788], a protocol used for
   flooding configuration information and assigning prefixes to links,
   combined with the Babel routing protocol [RFC6126bis].  Babel is an
   extensible, flexible and modular protocol: minimal implementations of
   Babel have been demonstrated that consist of a few hundred lines of
   code, while the "large" implementation includes support for a number
   of extensions and consists of over ten thousand lines of C code.

   This document consists of two parts.  The first specifies the exact
   subset of the Babel protocol and its extensions that is required by
   an implementation of the Homenet protocol suite.  The second
   specifies how HNCP interacts with Babel.

1.1.  Requirement Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
   "OPTIONAL" in this document are to be interpreted as described in BCP
   14 [RFC2119] [RFC8174] when, and only when, they appear in all
   capitals, as shown here.

1.2.  Background

   The Babel routing protocol and its extensions are defined in a number
   of documents:

   o  RFC 6126bis [RFC6126bis] defines the Babel routing protocol.  It
      allows Babel's control data to be carried either over link-local
      IPv6 or over IPv4, and in either case allows announcing both IPv4
